Itsuki’s Confession of Sin

"What's happening..." Itsuki was confused.

Shinichi stopped playing.

"Compared to this, do you know?"

He moved his lips towards her and spoke slowly and deliberately into her ear with a magnetic, tantalizing, and masculine voice.

"~~~"

As if an electric current surged into her ears, Itsuki's eyes widened in surprise, and her whole body trembled slightly.

She quickly steadied herself against the wall to avoid the embarrassing appearance of her weak legs.

"A-Asada-kun...?"

As those words came out of her mouth, Itsuki tightly closed her lips, her ears burning as hot as fire.

(Is this gentle tone really coming out of my mouth?!)

Ignoring her embarrassed and panicked expression, Shinichi continued to mimic the arrogant CEO's tone of voice.

"I once swore that if anyone dared to kabedon again, I would show them the dignity of a man."

The low and charming voice carried warm breaths, slowly approaching Itsuki.

Itsuki's heart pounded, she slightly parted her red lips.

"Well, what would you do if Uesugi-kun did it?"

Shinichi: "...?"

He suppressed the anger in his chest and gritted his teeth.

"I said 'he'! And can't you stop saying words like that which ruin the mood! Can't you learn from me?"

"You, how dare you... Fine, I won't say anything anymore." Stared at sharply by Shinichi up close, Itsuki had no choice but to shut her small mouth in sadness and stop speaking.

Then, she reacted and reflexively took a step back.

"No, Asada-kun, you...uh!? Uh-huh!"

She wasn't given time to escape.

Her reddened mouth was tightly shut, and he pulled his hand behind her head and let him hug her.

Shinichi held her head with his hand, smoothing the hair that obstructed, and without leaving any traces, he pressed her against the wall. He became the one doing the kabedon.

Itsuki resisted for a moment, then slowly softened, letting him taste as he pleased, and even taking the initiative to indulge him after she got used to it.

After experiencing so much, Shinichi was no longer the passive recipient of everything.

Because Itsuki took action first, he was impolite, and in his own home, it was certainly the best way to show the dignity of a man.

He didn't need to care about Itsuki's mood, because now it seemed like he had flipped some kind of switch. From the initial awkwardness and avoidance, to various skillful attempts and counterattacks later, the more he played, the more energetic he became.

"Uh-huh, uh... Wait, wouldn't it be better to change the angle?"

"What do you think?"

"If that's the case, let me try again, um... um, um, ah... Huh~ The angle is right, but it's really an unpleasant skill."

"I can't hold back. Besides, you haven't... been okay until now."

"...Hmph, don't say things like that which ruin the mood."

"...Itsuki, you truly are foolish."

"W-what! Asada-kun was the first to kiss me!"

"A first kiss can do this, Itsuki."

"Stop joking! I, I'm not a novice..."

"Oh?"

"...This is the first kiss. But, I worked with you!"

"If you say so, then why did you touch my stomach muscles?"

"You're different, you're very reckless!"

Itsuki stared at him angrily, her cheeks flushed, her eyes full of tears, and she looked very enticing.

Shinichi lowered his head and kissed her.

Itsuki's eyes slightly widened, then slowly closed, her hands wrapped around his neck, and she sank into the kiss different from before.

"..."

After a long time, Shinichi withdrew. Itsuki took a deep breath and buried her face in his chest. After hugging him tightly, her whole body gradually relaxed, and she listened to the beating of his heart.

Shinichi held her soft body tightly, stroking the back of her head with his palm.

Itsuki took a deep breath, it was clearly just the smell of clothes, but it was so calming that she didn't want to let go.

"...I never thought I would like someone so much."

She suddenly spoke, pressing her forehead against his chest, her voice slightly muffled.

"I never thought that even though I liked you so much, I would still accept the fact that you're not mine."

Shinichi said softly, "Forgive me."

"Is that all?"

"Not just that."

"Not just that." Itsuki hugged his waist tightly again and said loudly, "Sorry, it took you a lifetime to say it!"

"Yes, I will." Shinichi said with great certainty.

"In that case, are you fond of me?" She quickly changed the subject of conversation.

"Of course."

"How much do you like me?"

"It might be because you like me more." After Shinichi finished speaking, he stared at her with her face buried in his chest in surprise.

"Are you acting spoiled?"

Itsuki raised her head, looking very dissatisfied.

"Yes, I've loved you for a long time, and I don't know when the next opportunity to monopolize you will be. Why wouldn't I want to be more spoiled now?"

"Well, sure." Shinichi raised his hands in surrender, afraid that she would exert that strange power again and break his waist.

Seeing his attitude, Itsuki lowered her head to his chest and took a deep breath, then pulled her face away when she was satisfied.

"Asada-kun, may I call you by your name?"

"You can call me darling."

"I'm serious!"

When tenderness pressed on his stomach, Shinichi heard a cry from his spine.

"Sure, you can say it," Shinichi did his best to suppress the tremor in his voice and smiled.

"In that case... Shinichi-kun," Itsuki said softly.

"I'm here."

"I like you."

"I do too, Itsuki."

"What's our relationship now?"

"A lifelong relationship."

"Do you use this term for other girls?"

"How could I? Use it now and never repeat it."

"Huh... I slightly regret it, what should I do?"

"Um... it might be too late, unless I die young."

"Don't say cursed words like that. You took my first kiss. Please live until I stop liking you!"

Itsuki's grip tightened again, letting Shinichi smell the scent of young death.

He couldn't help but smile bitterly, "This love is very heavy."

"You called me fat again!" Instead of getting angry, Itsuki laughed, "But no matter how heavy it is, you won't easily discard it."

Seeing him, Itsuki spoke each word with a smile.

"Shinichi-kun, please give me your advice in the future!"

"Here's the same, please give me advice."

Shinichi replied.

Just like before, Itsuki always relied on Shinichi.

But now, she was still leaning against his chest, immersed in this warm season.

Today, Itsuki understood what she wanted to do.

So, be with the person she loves.

...Although this was a slightly strange love relationship, for some reason, it felt reassuring.

Because Shinichi promised that even if he died, he would never give up and become a scoundrel, and he would always cherish this relationship.

"...I just want to say that you deserve to be."

Shinichi was concentrating on holding her, and it felt like holding a warm pillow, he was almost falling asleep while standing, so he didn't hear clearly what Itsuki said.

"I won't tell you!" Itsuki stuck out her tongue, grinned mischievously, then tiptoed and stealthily kissed him.

"...Hey, what should I do? I feel a bit addicted."

Shinichi shook his head, his eyes showing a sadness he couldn't understand.

"Itsuki, it seems like the previous weight loss plan still failed to control your cravings."

"I-I just talked about weight loss! And also, don't make it sound like I'm lewd—!!!"

"Oh, naughty."

Except for Room 102, all the residents of the old apartment tonight lived in fear of the possibility of the building collapsing due to some unexplained tremors.
