OMG THIS WAS SO FUCKING CUTE AND MAYBE THE PERSON THEY WERE TALKING ABOUT WAS HIS BROTHER?

Nope. Chet Baker was a real life Jazz player that jumped from a second story hotel window in Amsterdam in 1988. Heroin and Cocaine were found in his room, no sign of a struggle.
Though, I do believe you are correct in that his brother also jumped to his death. So for Taey (sp?), it amounts to the same thing. He loved his brother, but hates him for killing himself. And has started hating anyone who killed themselves because he thinks they are weak. He also probably partially blames himself for not seeing it coming.
omg xDD the recent comment is also mine and I was talking about when he was younger xDDD but that comment still matches this chapter (=・ω・=)
