5.5..in high school, he was fat and fell in love with his senpai. he thought his senpai felt the same for him so he suggested giving his number but was rejected. heart broken, he got skinnier and is now in university hoping for revenge. but then he heard the guy dropped out...but all sudden, they are having sex...and then dating..and then realized that his crush actually liked him when they were in high school. addition that he has a fat fetish..plus, the guys ex showed up..
i think it would be interesting for kou chan to see the other side of chiaki.
ex cut his hair prob because he did like chiaki and now he is moving on.
