This is such a good trope to look for!
Grand Prince — He gets the throne and it drives him nearly crazy before he ultimately dies and realizes it wasn’t worth it.
The Tale of Nokdu — similar vibe to the one above
So I Married the Anti-Fan — he manages to steal almost everything from the ML but he finds now joy and then tragedy strikes and it’s too late for him to redeem himself
Lighter and Princess — he gets the company, the girl, the fame and everything he wants but it destroys him from the inside out leaving him alone in the end
Only Side by Side with You — similar vibe to the one above but it’s a female CEO instead
The Double — he kills (he thinks) the FL to protect his family and gain power from an evil princess but then realizes all he’s done was for nothing and the only one who ever loved him was the FL
