So I can't remember basically anything about this yaoi, except that the uke was a black (?) Haired boy who played violin and had some stuttering issues. I think he also worked as a cleaner in some company.
Thanks :"D

It's a yaoi and the storyline goes somehow like this: the uke used to be bullied in his old school, but the seme saved him once from his bullies so he fell in love with him. The uke also changed schools to the same school as the seme and he starts bullying semes childhood friend because he wants the seme to notice him. The uke had black hair I think?? And he was also rich?? The seme worked in a cafe/bar/restaurant??

Btw sorry for my bad explaining, but I just cant remember the story or it's name no matter gow hard I try! ;-; thank u sm if you can help me :"D
