Bet the possessive sunbae saw them(づ ̄ ³ ̄)づ

saw the raws and he will see them together and he'll kinda scold MC for hanging out with someone much older (translation might be off) also he's gonna end up jerking off coz of MC after hearing them (MC+ML) phone sexing on a bathroom stall, + he seems to be dating a girl who looks a lot like MC. So really strong likelihood that it's gonna be a love triangle.
