It is that one
Yessss, Thank You
I can't remember the title of this bl but here are some details about it:
MC is a is great and well known actor who died and got reincarnated to a blond actor who in the first chapter was seen sleeping with the ML.
ML is a businessman I think and is a big fan of the actor (before the reincarnation) and if I remember correctly was set up to sleep with the MC in the first chapter
MC before reincarnation was a Brunnete, well known actor, has a sister and died at a young age
MC, the blond one, was a new actor and was finding sponsors, i think
ML is a black haired guy who is a bussiness, maybe an owner/CEO of an agency
