I read a BL manhwa where the uke is like.. sleeping around and he has this friend he met in highschool(?) well not really a friend that person just sort of follows him around and thinks their friends and he calls the uke for advice with his relationships and yea. The ukes "friend" is also from a rich family. One day I think this was in the first chapter the uke gets a call from this "friend" and the friend asks him for advice about a guy he likes that like super handsome and the friend sleeps with him then one day the uke gets a call saying his "friend" died. Some people I think(?) thinks that his friend committed suicide but some police officers came to the ukes house saying there's a chance his friends death might not be suicide so they call the uke to the police station and asks him about stuff there he meets the guy his friend was talking about yknow the one who he slept with. Also I forgot to mention the guy his friends sleeps with is straight.
That's all I know so far and the male lead is a TOTAL . Sorry if it's too long ( ̄∇ ̄")
