Long story short. (Even if u don't need it)
Pink hair guy is the leader of the group and black hair guy is whom he looks up too. Black hair guy sees the pink hair guy from utube before he debutted and remembers how hard he worked and works.
Pink hair guy and black hair guy in the later future both teams compete and Black hair guy's group won which led to pink hair guy feeling bad for not being good enough. Black hair guy helps pink hair guy to stand out on the stage by acting close with him.(To give him the fame and attention he deserves for how hard he works)
The attention worked and pink hair guy now is getting the attention. Later on so and so happened (with the black hair guy always helping the pink guy out) and pink hair guy realized he likes black hair guy. But during such intervals pink hair guy is SA'ed (just uncomfortable touch) and continue and also hit by his teenage kidnapping case trauma but black hair guy didn't know and so he introduces his brother who is a psychiatrist to pink hair guy and later fjnds out about pink hair guy's trauma from his brother due to misunderstanding and unknowingly.
Aaah thank you so much for this
I hope the "pink hair guy, black hair guy" thingy wasn't confusing because I'm honestly bad at names. (I could have even used ML and MC but I'm ahhh dumbo)
