Today, it was after school and Kotonoha was on her way to the school roof to meet up with Makoto to spend some time together. Makoto was the one who suggested it and Kotonoha, while not understanding it, went with it cause she didn't see any harm in it. 

Course there wasn't any sexual going on, much to Makoto's chagrin. Just a couple hanging out, talking, maybe a few cuddles, and playing handheld games together but that was it. 

Today, Kotonoha thought it would be no different from any other day but that wasn't the case. 

When Kotonoha made it to the door leading to the school roof, what she saw through the window made her eyes widen and her heart skip a beat. 

It was her boyfriend Makoto, and Sekai, Flukey's girlfriend, were having sex on the school roof. 

A surge of pain and sadness crept into Kotonoha's body as she just stayed silent and left them to it as she left. 

Any other person who knew their worth would've confronted their other half cheating on them, but Kotonoha had another idea in mind. 

She believed that she just needed to try harder to keep Makoto. 

And as for Flukey, if Kotonoha manages to get Makoto away from Sekai then she'll give more of herself to him and spend more time with him. 

It was a good plan, or at least Kotonoha thought it was.

As she left, she came across Flukey. 

Flukey: Oh hey Kotonoha. I was wondering if you've seen Sekai anywhere? I can't seem to find her and she's not taking my calls or my texts. She's not with Makoto is she? 

Kotonoha was well aware of the fact that Flukey didn't like Makoto in the slightest but kept his personal feelings about it to himself. 

Kotonoha: Oh um she told me that she had some errands to run so she can't spend time with you today. 

Flukey, having no reason not to believe Kotonoha, believed her lie. 

Flukey: Huh. Well she could've called and told me that or text me back that she was going on errands. Well alright then. Where's Makoto then? Shouldn't he be with you?

Kotonoha: He told me that he had family matters to deal with. 

Flukey: Oh. Well do you wanna hang out today then? That's if you're not busy. 

Kotonoha: *Nods* Sure. 

With that, Flukey and Kotonoha left the premises.

With Makoto and Sekai....

After Makoto and Sekai were done having sex, he was the first to leave while Sekai stayed on the school roof, thinking about what she just did. 

While she knew that what she did was wrong in every sense of the word, she couldn't deny her feelings. 

Sekai: (I'm so sorry Flukey. I do love you....but I love Makoto more)

With that in mind, Sekai got up and made sure she was clean, or as clean as can be, before she left the school roof, trying not to let the guilt of her cheating overtake her. 

But what she doesn't know, is that guilt can be just as contagious as a disease.
