It's a manhua where the story is a bit like black lotus but instead the male mc is a badass right from the get go and the ml does a 180 as soon as he's gone. UGGHHAHSJSHSJDJD WHATS IT CALLEDDDDJDHDJDHJSDHBD

Ml (dark blue hair?) Is abusive and breaks mc's piano which he got from his mum.
Ml is also cheating w some blond haired dude and blames mc for everything bad in his life
Mc leaves but Ml is like "why pls don't leave I'll be good

Why does this remind me of a certain manhwa
