Confused why there's all this Mafuyu hate. The kid has a rocky relationship with music and therefore will have a bit of a rocky thing with his personal relationship that does have a connection with music. The poor guy felt like music was the reason him and his late boyfriend were growing a part and then also in turns feels responsible for said late boyfriend's death. Let the child be traumatised, not to mention this all happened while he's a teenager. I do wish that their relationship got explored more and had a more healthy line of communication but nothing can be done now
