they did actually say why multiple time but its fine dont sweat it :3 the bf (Yuki) knew mafuyu loves music so he wanted to prepare him a song so he joined a band but that didnt leave the couple much time to hang out so mafuyu got mad and they had a fight, mafuyu then asked yuki if he would die for him not knowing that he will actually do that (not sure how he commited suicide, that part i need help with)

Yeah, he hung himself under the influence of alcohol after his fight with Mafuyu. But that doesn't mean he really wanted to die. He was just too drunk to realise.

I think he didn't know... I could be call a person that is not "mentally stable", and believe me, the clues are there, and people around me noticed one of two things but they are never really sure about anything... I wasn't really sure about anything myself until recently.
Maybe not even Yuuki knew he was that way. I suspect that Yuuki was bipolar (By the way they describe him), and that is one of the most difficult diagnosis, since you have periods of really up and periods of really down moments, people see it like you are ·moody· and stuff like that. Normal people don't hang themselves just because they are drunk and sad because they fought with their partners :/
Why did his first boyfriend did commit not alive? Or they didnt tell why?
Or i am dumb
Pls help
