There was a guy at school that you liked. However, he is popular, rich and usually kept his distance from everyone, so you didn't even think that you could attract his attention, but it turned out that he was interested in you.

You talked sweetly, walked quite often and spent time together, but there was one "but".

You were at his house right now, doing homework together, until Dazai started touching you in a very ambiguous way, hinting. And everything would be fine, but you've been pretending to be a girl all this time because Dazai was homophobic.
