"The whole Eku situation is this-- He was going through some relationship trouble and fighting a losing battle against his insecurities and gender dysphoria, since the day I met him like 3-4 years ago, he'd been constantly trying to kill himself while in a drunken haze. But he always failed spectacularly, honestly at some point I started thinking it was just for attention. But in Summer/Fall of last year, he started calling me a lot to vent about the woman that he was living with and the shit that she did to exacerbate his insecurities. At some point he stopped calling me. Then a mutual friend called me about an hour and a half ago, and told me that they found his body in his room with the door open at about 17:10 on Friday"
Goodbye senpai, you will be missed.
