I think its still to early to make assumptions, we dont know how long Sanyu knew about this. It could literally have been the night MC choose to off himself, that Sanyu found out. And the shock the MC felt when a member from his band saw him in that condition, could have been the last straw.
I have not read the novel, so I dont know, but all im saying is; we dont have enough details. (=・ω・=)
Actually almost all of the members are bystanders but ye i hate sanyu the most for knowing the most about his situation but hasnt done anything (as far as we know). I just wish he couldve gathered evidence against who ever the hell the ex is.
I revoke my statement after reading the spoilers from below lmao i hve know learned a lot
what happened? spoil mee
I really hate Sanyu for being a bystander. Like- he could've said something. He could've settle the tension between the members and he could've comfort the mc but nah. Im sorry but Im still pissed about that ex and it could've been prevented if the MC has someone to talk to and give him good advice or something
