Your childhood friend

"Rei-senpai?" 

How could Isao not be surprised?

The one who came was the main heroine, whose heart should be loyal to the protagonist, yet this young woman came to his room quietly, alone. 

Well, this heroine wasn't exactly loyal since she dated the protagonist's best friend, but since that best friend passed away after being bitten by those "things," she should return to the protagonist's arm, right?

Yet, why did she come to this room?

Did she wish to return to his arms instead?

"Sorry for disturbing you, Iinuma-kun." 

Rei showed an awkward smile when she apologized. She could even see his surprised expression because she had come, but this was something that she had decided. 

"Can-Can I come in?" 

Still, with an awkward expression on her face, Rei asked nervously. 

"...sure." 

After a moment of hesitation, Isao nodded, letting Rei in, and closed the door quietly so as not to attract the attention of the others. "Is there something bothering you, Senpai?" He could tell that Rei had something that she was worried about, and naturally, as a good person, he was going to help to erase that worry. 

'As expected, being a good person is good,' he thought. 

"Sorry for bothering you at night. Are you about to sleep?" 

Nevertheless, Rei became even more awkward due to his gentleness, and at the same time, she wondered why she had decided to come. Frankly, there were many things that she wanted to say to him, whether it was her worry or about how grateful she was toward him, especially when she knew how selfish she had been previously. 

After all, at the school previously, she asked Isao to help Takashi, who had betrayed everyone and even caused trouble to all of them so that they were almost bitten by those "things." Moreover, her request also exposed Isao to danger and might even turn him into one of those "things." 

Lastly, she also thought that Isao might even feel guilty after the death of Shido, who made a stupid move and killed himself along with everyone. She wanted to make sure that Isao was okay and didn't blame himself for all of that. 

Yet, for the last one, she thought that she might overthink since Shido and the rest were a beast in human clothing, so no one cared much, even if they died. 

Still, no matter what her purpose was, Rei knew that her actions were bold and that she might even cause a misunderstanding among many, yet she didn't mind having him misunderstand her purpose. 

"It's fine. It's hard to sleep after all of that, after all." Isao didn't show much impatience toward Rei. After all, Rei was a beautiful young woman. Moreover, he was also curious about what Rei planned to do. 

Yet, when he saw her gentle and shy gaze, he felt like something was shaken within him. 

'It's come again.' 

Isao shook his head as he chanted that he was going to become a good guy, so he had to erase his bad hobby. Kyoko was enough; there was no need to add more victims, he thought. Yet, doing that was easier than being told. The act that was natural and happiest for him was impossible to be erased so suddenly. 

However, Rei's actions stunned him. 

"I am sorry!" 

Rei suddenly apologized and prostrated herself. 

"...what are you doing?" 

Watching how one of the heroines of the story suddenly prostrated before him, Isao felt strange. 

"I... have caused you many problems. If it isn't because of me and... Takashi... then your trip will be smooth." 

Frankly, Rei felt like everyone was just a burden for Isao. 

If Isao wanted to, he would be able to leave without everyone smoothly. Yet, he still decided to stay and even helped all of them. The rest aside, she knew that the ones who had caused him so many problems were both her and Takashi, her childhood friend. 

Rei knew that she had caused so many problems, yet she still came to him shamelessly and even inwardly, wishing to ask for his help, especially when she wanted to know about her parents. 

Knowing all of that, she felt how detestable she was, and she felt so ashamed. 

"Get up. Don't apologize like this." 

The words "thanks" were better than apologizing, yet Isao wondered why everyone in this country loved to apologize to show their submission.

Isao also decided to become a good guy, and he knew how tough being a good guy was, so he never thought of blaming others since this was something that he had decided to do. 

Yet, Rei didn't intend to get up and stayed prostated toward him. 

"Don't be like this, Senpai." 

Isao was helpless and approached Rei, holding her soft arms with his hands. Still, when he approached her, the long hair on her back was slightly parted open, showing her white nape. Her scent was sweet but also slightly sour, as she hadn't changed her uniform and was full of sweat. Yet, strangely enough, instead of being disgusted, her scent brought a certain charm. 

Was this the power of the heroine?

Yet Isao held himself, pulling her to get up. 

However, being touched by Isao, Rei felt her body was hot, and she felt a strange sensation so suddenly on her body. Being pulled, she didn't fight him and let him pull her while lowering her head since she didn't want him to see how reddened her face was at that moment. 

Nevertheless, when he pulled her up, Rei felt her legs were weak by either exhaustion, relief, or just numbness as she had stayed in an uncomfortable position for so long, causing her to fall on his arms. 

Isao was startled and looked at Rei, who lay on his chest so close that he could feel the softness of her chest. Her ample breasts, which kept shaking during their trip, were soon pressed tightly against his chest. 

"...Senpai?" 

Rei didn't answer him but only hugged him quietly since Isao made her feel much, much more comfortable than her childhood friend. Compared to her unreliable childhood friend, who even abandoned her and everyone else, Isao decided to save all of them without leaving anyone behind. Moreover, as a woman, she needed someone to rely on at this moment. 

Her boyfriend died, and her childhood friend was so unreliable. 

Who could she rely on except for Isao?

Yet, when she hugged him, she saw a reaction on his penis, an erection that was impossible to hide. 

The silence between them became ambiguously awkward. 

Rei, who had always lowered her head, raised her head to look at him. 

Isao couldn't see her eyes, so she looked away. "Sorry, you are attractive, after all." 

Rei was silent, but instead of moving away, she hugged him tighter. 

"Senpai?" 

"It's okay. If it's you... I don't mind." 

Her voice was soft and meek. 

Once again, instead of her childhood friend, Rei chose someone else. 

This time, Isao didn't look away. He looked at the beautiful young woman in his arms. She was weak and needed someone to support her. At the same time, she was so naive, thinking all of his actions were sincere and wished to help everyone, but watching her like this, as a good person, how could he leave her?

Her trembling body was fearing for her future and worried about her family.

Except for her lewd body and beautiful face, Rei knew that she couldn't offer him anything, but she forgot. The immorality that came from taking the childhood friend of the protagonist and her dead boyfriend was something that she could only offer. Such traits didn't exist in the rest.

Only her. 

However, Isao didn't do his actions because of lust. This girl was scared, and he knew that, as a good person, he had to hold her. 

"Senpai..." 

Holding her cheek softly, Isao moved closer. 

Shy, Rei blushed, but instead of pulling her head or looking away, she closed her eyes, feeling his lips that touched against hers. 

Yet, if it was the protagonist or her dead boyfriend, it might be the end. 

However, for Isao, this was only the beginning. 

Holding her in his arms, he moved her into his bed and took the condom that he had taken from the convenience store before. 

"Hmn~!" 

While the two comforted each other during this horrible time, Rei wasn't the only girl who wanted to be comforted by Isao. 

Miku Yuuki felt scared, and tonight, she wanted to hug Isao, yet when she was about to go to his room, someone stopped her. 

"You bitch, what are you doing here?" Saya looked at Miku, who walked sneakily like a thief angrily. 

Miku was awkward and wanted to get angry at Saya, but when she thought that this was Saya's house, she knew that she couldn't antagonize her. "I-I am a bit scared. I want to talk with Isao-kun..." 

"No way! I won't let you sleep with him, slut!" 

"Who is slut?!" This time, Miku couldn't control her temper. "Aren't you the same? You came here because you wanted to sleep with him, right?" 

"Wh-Who wants to sleep with him?! I-I just want to talk with him!" 

"Oh, you are still a virgin?" 

"Shut up!" 

As the two started to bicker, the rest, who wanted to go to Isao's room, were speechless. 

Yet, with this commotion, it was definitely impossible to go to Isao's room. 

However, the girls and the female weren't the only ones who came out of their room. 

Takashi walked out of his room and went to the room where her childhood was staying. 

"Rei, are you there?" 

"...." 

"Rei? Are you sleeping?" 

Takashi sighed at the night sky, thinking Rei and the others might be asleep. 'Let's talk to her tomorrow.' 

Yes, Rei was sleeping, but she definitely didn't sleep with the rest of the female group. 

Yet, it didn't matter since there was no need for Takashi to know what she was doing at that moment. 

---

Sorry for the others, but as a good person, this is something that Isao has to do.
