So you're my sister-in-law

Until school hours ended, school went on as usual.

Lilith who could hear his inner voice did not immediately question him, she immediately left and said goodbye to her classmates.

Eiji was in no hurry to seduce the girl because even if he didn't take the initiative, Lilith would come to him.

He had examined several plots in the future using his "Future Insight" ability and knew what exactly the girl wanted from him.

As Miss System had said, the multiverse was in chaos.

It wouldn't be surprising that there were many transmigrators with systems that changed the plots of the original works out there.

"Eiji, this is bad! Hurry up and hide!"

And as he said, everything was fine until school hours ended and he was walking towards the Service Club with Hachiman who happened to meet him on the way.

However, before they reached the club. Yukino ran from the direction of the club and held his hand frantically.

"...." Hachiman wondered if he should continue walking to the club or stay here while the two fed him dog food?

The protagonist felt sour.

Although he didn't know the original work, Yukino was his heroine and now the girl was so close to another man.

... Actually Yukino had already been eaten by Eiji. So it was natural for the protagonist to feel uncomfortable, right?

"Yukino, calm down... Is someone bullying you? Who would dare to do so? Depending on what that person does, I won't kill him."

{We have so-called laws in this society, even if that person is bullying Yukino, don't kill people carelessly! Yukino, you have to stop Eiji.}

Protagonist Hachiman has an inner drama in his heart.

Unlike Basara's protagonist, he is still a Rom-Com protagonist whose moral standards are limited by the laws made by the general society.

At this point, Eiji was one of his few friends who could be counted by one hand, so he was a little worried what the boy wanted to do.

Yukino certainly heard what Hachiman said in his heart, she shook her head.

"It would be fine if it was someone else, but it's not. This person is my older sister, she came to the service club to meet you."

"So it's Yukino's older sister? I'm going to greet my sister-in-law."

"Don't!"

Eiji was confused, why, isn't my sister-in-law beautiful?

Yukino would punch her boyfriend in the head if she knew he was thinking of her older sister.

She hugged Eiji as if to prevent him from going to the club.

"...." Hachiman.

{Should I go? Hey I should go instead of watching this, right? I'm going.}

Hachiman wanted to continue to the club and he was also curious what Yukino's older sister was like to make Yukino so afraid of her.

However, Eiji grabbed his shoulder which made him unable to move.

Hachiman glanced at the boy who did that while hugging Yukino with one of his hands with his dead fish eyes that had a question mark.

{Eiji, don't tell me you want me to watch you cuddle with your girlfriend? You bastard! Let me go!}

The heroines:

What fun thing are you guys doing?

Yukino's lips twitched. However, she ignored Hachiman and just stared at Eiji's handsome face.

[Hachiman, you want to go see my sister-in-law without me? I won't let you!]

So that's the reason you're holding Hachiman back?

Yukino started to worry. Couldn't Eiji be thinking about her sister as well? The thing that scared Yukino was that she already knew the answer and actually felt it was normal.

After all, her older sister was no less beautiful than her.

"Yukino, why can't I see my sister-in-law?" Eiji asked while hugging Yukino's slender waist.

Yukino rolled her eyes, "Don't talk here, get to class!"

She pulled the big man, Eiji to an empty classroom that was located quite far from the service club. Of course, Eiji brought his friend, Hachiman along with him.

"I don't have to come, right? I..."

"Hachiman, be quiet and don't interrupt me. By the way, please keep an eye on the situation outside from the door window."

Yukino pleaded with Hachiman, but the boy felt that the girl was ordering him around.

Even so, he did not refuse and did so.

"...." Eiji felt sorry for the protagonist, he would treat him to a meal next time. He would also ask Miss System to give the sub-system installed in the boy something rather nice to pass on to him.

Miss System: "...."

Do I have to pay two people now?

Well, I have a lot of things that aren't useful for my host but are useful for ordinary people here.

Something like a copy of a good song or novel for example. That would be worth some money in this world.

"Eiji, I don't want you to meet Nee-san now because she's definitely coming to question you about the things you did to me..."

Yukino suddenly blushed, her voice getting smaller.

"What? Did what?" Eiji pretended to be confused.

"You! You know what you did to me..."

Yukino glared at Eiji, she started pinching the boy's waist.

Her gaze was trying to say 'Try to remember!' to her boyfriend.

"Is this about Yukino's weakness?"

"My weakness?" Now it was Yukino's turn to be confused.

Hachiman who was listening to their conversation from the door was curious.

Yukino's weakness? What was it?

"Yes, your weakness for cats for example. Every time you meet a cat, especially a kitten on the street, you can't resist feeding it with the cat food you carry every day in your school bag."

"That's not it! Eiji don't joke around, you can't say that! Also, how do you know I keep cat food in... Forget it!"

Yukino's cheeks turned red, she was so embarrassed to hear her little secret known. Eiji was fine because he was her boyfriend, but what about Hachiman listening to their conversation?

She glared at the boy with a cold stare.

You should also forget what you just heard and don't tell anyone.

"...." Hachiman who understood what Yukino said from her gaze hurriedly nodded.

He felt a chill on his back just because of Yukino's sharp gaze.

That was definitely not the effect of an ordinary person's gaze!

Hachiman did not know about the Master-Servant contract around Yukino's neck. Now Yukino was basically not an ordinary person.

Eiji scratched his brow before asking his girlfriend. "So what's the problem?"

"Eiji, you... You really want me to be the one to say it, right? That's what you did two weeks ago, w-we did it in class when everyone had gone home."

Eiji widened his eyes as if he just remembered what Yukino meant.

If possible Hachiman didn't want to hear what Eiji said next.

"Did Yukino's older sister come to see me because I stole her younger sister's virginity before marriage?"

"!!!" Hachiman was dumbfounded.

{You've gone that far?!}

Yukino nodded with her earlobes turning red.

Although she was reluctant to let Hachiman hear it because it was embarrassing, but the boy's presence was needed to guard the door.

"Yes."

"You told her? Don't get me wrong, even if you do, I will be responsible for marrying you after we graduate high school."

"No, not me..." Still, Yukino was happy to hear what the boy said about responsibility.

Although her boyfriend would definitely marry many women other than her.

Ever since losing her virginity in Eiji's hands, she knew her body and heart were conquered by that boy.

She reluctantly agreed to share her husband with another woman.

"Then who?" Eiji asked.

Yukino pursed her lips before saying unhappily. "That's my childhood friend, Hayato Hayama. During my lunch break, he came to the service club to ask about my relationship with you. I answered him honestly, but he..."

Yukino made a disgusted expression on her pretty face.

"He thinks I've been tricked by you and tells me that you're not a good person even though it's true, but I–"

[Yukino? You're defending your boyfriend, right? When have I ever tricked my woman into sleeping with me? If you're talking about my charms making you unable to resist, that's not wrong. And yes I'm not a good person, I've never thought of myself as a good person hey this is troublesome.]

The heroines: "...."

Yukino continued what she said, she didn't bother commenting on Eiji's inner voice because what he said was true.

"I'm not refuting what he said. Even so, when Hayato got excited and told me to stay away from you, I slapped him by saying — Impossible, who do you think you are? Hayato, stop meddling in my affairs, we're not that close. I like Eiji and I'm not going to leave him just because he's not a good person, precisely because I know how good he is, I've left everything to him."

[I'll pretend I didn't hear that line about how good I am. That's cool, Yukino! At least I won't have to slap that boy named Hayato unless he takes the initiative to come to me.]

{I witnessed it firsthand during my lunch break with Yuigahama at the service club. It was very satisfying to see that blonde Ikemen get slapped by Yukino and leave with an ugly expression on his handsome face.}

[Protagonist, did you see that hot-blooded scene? Tsk! Too bad I wasn't there, I was having lunch with Lala and the others...]

Hey, you guys aren't really communicating through inner voices, are you?

The heroines were surprised.

Is it just them or do Eiji and protagonist Hachiman have a good relationship?

Protagonists Basara and Rito would be jealous of Hachiman.

No, what were they thinking?

For a moment, Yukino made a strange expression.

"Then what does this have to do with your older sister? Don't tell me that boy told your older sister about this?" Eiji asked and actually he was sure his guess was right.

Yukino nodded. "He did, actually he got engaged to my older sister because of our family's condition even though Nee-san didn't like it and was just doing her duty as the heir of the Yukinsohita family... Eiji why are you smiling?"

She looked at her boyfriend suspiciously.

Eiji pretended to cough, "It's okay, Yukino. I just thought I should know what kind of person my sister-in-law is before the two of us meet."

"Really?"

"That's right."

"...." Yukino paused for a while before continuing what she was saying. "That's why it's not impossible for Hayato to contact my sister-in-law and tell her everything that happened."

The room was silent.

Looking at Eiji and Yukino who were standing face to face beside the window emitting the afternoon light, Hachiman felt like he was looking at the protagonist and heroine of a school and romance-themed anime.

Everything he heard didn't help either, making him think this was a drama plot!

Of course, the single Hachiman was uncomfortable watching the scene.

{Can you guys do it quickly? Don't torture a girlfriendless person like me any more than this!}

When the protagonist in the original work complained.

He didn't realize a woman was already standing outside the door.

And when he realized it, he almost jumped back in shock!

Just then the classroom door slid open.

"Yukino~ You said you went to the toilet, but you're here alone with two boys? Mom will definitely be angry if she finds out you don't take good care of yourself from the opposite sex."

"Nee-san?!"

Yukino's face was panicked, although she was now physically much stronger than her older sister due to the Master-Servant contract, she still lacked the confidence to face her older sister in this situation.

She unconsciously hid behind Eiji.

"Ara? To make my Yukino who is usually a loner and doesn't like to rely on others start relying on other people's backs..."

The woman with shoulder-length black hair and a face as beautiful as Yukino's walked up to Eiji and Yukino.

Her figure wrapped in a white cardigan that displayed her cleavage and white shoulders, a short blue skirt, black stockings and square earrings in her ears made her look glamorous and accentuated her figure that was more wavy than Yukino.

If Yukinoshita was an ice cube, this woman was like a small sun that shone on the people around her and made people approach her easily.

She ignored Hachiman who swallowed and stood two steps in front of Eiji.

"You must be Yukino's boyfriend, Eiji Seiya, right?" Haruno smiled kindly at the boy in front of her.

Eiji also smiled and said, "It's me, you must be Yukino's older sister?"

"Right~ I'm Haruno Yukinoshita, nice to meet you, Eiji-kun. You're as handsome as I heard."

"Thank you, sister-in-law is also very beautiful."

"Sister-in-law? Fufufu. Isn't that too soon?"

Haruno didn't expect Yukino's boyfriend to be braver than she thought.

Yukino stared at her from behind the boy without fear even though she panicked earlier when she saw her older sister finding her hiding here.

'Interesting, he was even able to make Yukino feel safe. What kind of drug did he give my little sister? Hayato said this boy is a playboy and has relationships with many women.'

'And is he really...'

Haruno's violet eyes hid a chill.

Eiji certainly realized it, he even knew what kind of person her older sister Yukino was in the original work.

He asked Miss System to do it as usual before complaining in his heart.

[A little sister controller more troublesome than Serafall has appeared. At least if it's Serafall, I can still persuade her by giving her a magical girl dress.]

[Serafall is so easy.]

Serafall: "Levia-tan isn't easy!

Sona: "You're easy, Onee-san."

[But Haruno is... This woman always pretends to smile when she doesn't feel like smiling and pretends to be friendly even when she's angry.]

[She's a pitiful woman... As the eldest daughter of the Yukinoshita family, unlike Yukino who was given a lot of freedom— from childhood until now Haruno has always obeyed her parents' wishes in all matters. She did that too so that Yukino wouldn't get involved in their family affairs.]

[She often wears a mask most of the time like now and hardly ever shows her true feelings to anyone. As a result of all that, her psychology is somewhat distorted.]

[For example now, she hides her murderous intent and obsession to destroy the person who took her younger sister's virginity.]

The heroines.

Isn't that you, Eiji? You who took Yukino's virginity!

Yukino was also helpless and shocked because she just found out that her older sister had actually lived a harder life than her. She always thought her older sister was the pride of her family and before meeting Eiji, she always wanted to be like Haruno.

But because Eiji said that, Haruno in front of her looked pitiful.

Yukino was also worried about Haruno's murderous intentions towards Eiji.

'Because Eiji is so familiar with my older sister. Is Nee-san also a heroine?'

She suddenly thought of this, and observed Haruno's expression which now suddenly became dazed.

That woman must have just heard it, right?

The proof was that she was staring blankly at Eiji.

"What did you just..."

"Ah sorry, I just got lost in my thoughts from seeing sister-in-law for the first time. I know it's too soon, but it doesn't hurt to get used to it early, right? Sooner or later we'll become a family. But of course if you feel uncomfortable with me calling you sister-in-law, I can call you Haruno."

Eiji didn't play like the protagonist Hachiman who first met Haruno for the first time in the original work.

He shamelessly called Haruno by her first name.

Putting aside Yukino who was already used to Eiji's shamelessness.

Hachiman couldn't help but admire Eiji who in this situation wasn't intimidated by her older sister Yukino's aura!

If it was him, he would definitely be nervous, especially when looking at Haruno's smile and her words which so far actually felt cold and emotionless even though on the surface she looked very friendly.

Just like Eiji, Hachiman was also not fooled by Haruno's mask.

In short this woman was scarier than Yukino in her iceberg mode.

"Pfft-, ahahaha!"

Hiss!

Hachiman stepped back. The woman suddenly laughed and it didn't seem to be a fake laugh.

Haruno was really laughing but in the dark atmosphere of this room her laughter sounded rather frightening.

Why was she laughing? Of course it was because of what she had just heard!

She was sure she had just heard Eiji's voice even though she didn't open her mouth when it happened. That boy somehow knew a lot about her, even her life experiences.

Now she suspected this boy had ulterior motives to get close to her younger sister which made her even more wary of him.

However, what he said earlier sounded like he was pitying her. Haruno felt uncomfortable, this boy didn't seem as evil as Hayato said. Of course from the way he dared to flirt with her in front of Yukino and the other woman's name he mentioned earlier, it wouldn't be wrong to think Yukino found a bad boy as her boyfriend.

Even so, what did she really hear earlier?

Could it be his thoughts? His inner voice?

Whatever it was, for now...

"Eiji-kun, sure. You can call me Haruno, but how would you know?" Haruno was still smiling falsely, she hid her true feelings well.

Eiji tilted his head slightly. "Know? Know what? Haruno... Oh you mean that fake smile of yours?"

"...." Haruno narrowed her eyes.

"There was also murderous intent in your eyes when you looked at me earlier. Haruno, you must have misunderstood me."

"What misunderstanding? You've taken my little sister's virginity, right? And although you're dating Yukino, I heard you're also dating other girls in this school, Eiji-kun."

Haruno stopped smiling, her beautiful face became expressionless which made Yukino nervous.

At this moment, she knew her older sister had ripped off her mask.

There was a swallowing sound in the room that actually came from the protagonist Hachiman.

But faced with this kind of situation, Eiji did not panic.

He nodded.

"What Haruno said is right. Besides Yukino, I actually have several fiancés and girlfriends."

"Not only several girlfriends, you also have several fiancés? Eiji-kun..." Haruno's chest rose and fell, she was about to explode at the thought of her little sister being eaten by a bastard!

But before she finished her words, Eiji interrupted her.

"I did but Haruno, Yukino knows about this and she has no problem with it."

"Impossible! Yukino, this boy is lying, right?" Haruno asked her younger sister, and seeing that the girl was not surprised by what Eiji said...

Haruno was dizzy, she wondered if Yukino was crazy?

Yukino's lips twitched, honestly I don't want to share my man with another woman either but things happened already.

Haruno didn't understand the world of heroines had fierce competition.

It's impossible to monopolize Eiji and if you give up just because you don't want to share with other women, you'll be considered a loser by the other heroine!

Especially by the women in the group chat, they would probably antagonize her and mock her every day.

Besides, she who was already in love with Eiji didn't want to lose to the other heroine! So the only alternative was to join his harem.

Yukino couldn't say any of this to her older sister, at least for now.

"Eiji's not lying, Nee-san."

"Yukino-"

"Wait a minute! Don't interrupt me yet. Nee-san... I don't know what Hayato told you, he clearly exaggerated his story."

"...." Haruno.

"Yahallo! I've been waiting for you guys at the club for so long, it turns out you're gathered here. What are you-" Yuigahama suddenly appeared at the door and was about to ask but Hachiman hurriedly signaled to shut up!

The dumpling-haired girl fell silent. Luckily her EQ was online, she noticed the horror atmosphere in the classroom and chose to watch from the doorway.

Yukino massaged her forehead, why did the number of spectators increase?

Glancing at the almost setting sun, she walked up to her older sister and said: "Nee-san, we should go home soon, I can explain everything to you at home."

"You must also be tired after helping mom's work at the company and bothering to come to my school."

Her younger sister, Yukino changed her personality. She was not as cold as usual, instead she took her older sister's hand gently and spoke softly.

"Eh Yukino?" Haruno was dumbfounded, she was definitely not used to Yukino being gentle with her. Or rather this was the first time something like this had happened since the girl graduated from elementary school!

'Is it because of this boy?'

Haruno looked at the very handsome Eiji complicatedly.

That boy didn't seem to realize his inner voice could be heard by her.

At first she wanted to ask why she could hear his inner voice? But forget it. Although she didn't know why this supernatural thing could happen to her, Haruno quickly accepted it and thought she could utilize this to find out what kind of person Eiji Seiya was.

And actually now she had confirmed that the boy had really taken her younger sister's virginity.

Haruno was worried, her mother would definitely scold Yukino severely if she found out about this. After all, if this kind of thing didn't happen— as the daughter of the Yukinoshita family, Yukino would inevitably become a tool for her family's political marriage in the future.

Haruno smiled wryly.

"Yukino, you better have a good explanation to convince me not to tell our mother tonight."

"I know, nee-san."

Yukino said confidently.

Haruno had no idea where the girl's confidence came from.
