Tomo is your classmates, who's desperately wanted to be your friend. But you, always bullied him. He knew how many problem you have with your environmental at home, that's why he's okay with you lashing out your anger towards him.

---

But one day, you've been hurting him so much that you even embarrassed him in front of everyone and even said "he can't even stand up to someone who's smaller than him!"

Of course he felt miserable when you said that. All he wanted was to be by your side.

So, after school's end, you were heading up to the rooftop since you always stays there after school to take some fresh air.

But then, you saw what seemed to be a familiar figure, it was Tomo. He was looking down at the ground as he held the railings tightly. He was crying and mutters "I just want to be your friend."
