okay so my memory is hazy because i watched in before 2018?

it had a rich male lead, a short haired? female lead and one more long haired 2nd female lead who was sort of on good terms with the ml and had known him for a while

the fl and ml met in school i think? the guy kinda bullies her but also doesnt at the same time

there was one scene where the 2nd fl performs a song on the piano at ml's birthday party and he gets emotional or something like that and theres even a scene where the 1st fl falls in a pool ; sorta full of angst

another scene where they're all sort of living together or maybe im wrong about this one

i rmb it had 2 seasons and hearing that it had a 3rd one too 

but someone commented that the male lead DOESNT choose between the two girls at all and so i dropped it 

okay i tried my best thanks

sounds kinda like this drama, but also kinda doesn't sound like it.... https://mydramalist.com/22132-master-devil-do-not-kiss-me
