Kotaro never made any sens then. He's just plain and nice. Very nice. And plain. That's all he has ever been. Ah and strangely madly in love with a guy that seems to share nothing with him. That has nothing to do with Kyujo who is, on the contrary, a more complex character (but hum, still very cliche) which is used to have everything he wants and seems to be very bored with life already... Kotaro can only see good in others as he is portrayed as a naive, cute and nice guy. How could he be able to not feel bad for Kyujo ?? This manga has just an original way to accumulate cliche...
Chill...It's just a story. If you can't separate fiction from reality, there is no way you can enjoy reading any type romance. All the characters will be bland. Stop being PC about the story.
Kyujo tried to commit rape and the only reason he didn't is because Ayumi saved Kotaro. He didn't just stop by himself and would have really raped him if not for Ayumi! Rape is a crime punishable by years in prison, but they just brush it off as if it's not important or it never happened. Then the rapist got burned a little by ACCIDENT when he came UNINVITED in Ayumi's house while Ayumi wasn't home (and he even pushed his way in). And now Kotaro has to repay him and service him because of that little ACCIDENT. I don't remember the rapist trying to repay Kotaro in any way for what he did. And i think RAPE is much worse than an accident you had no control over. This situation doesn't make sence. Kotaro's character doesn't make any sense anymore...
