there are few events, one is when he was young and accidentally injured a friend which led that friend to quit the piano. the second is with another friend at a later stage in life, he has a crush on that friend and one day, the friend asked him to miss some notes while at a competition so he can win and get a scholarship or sth. so yeah, he's had a bad luck w friends, I won't spoil any updates regarding how things were solved with them tho.
the last one is confusing to me personally but I think his relationship to his family, his mom in particular, is strange, there are no major events but that's the vibe I got.
Y'all spoil me pls. What are the past events the bottom it's suffering from?
