Looking for korean BL

What i can vaguely remember that mc dies and end up in someone's body which is a rich boy but his life is miserable (he attempt to k1ll himself multiple time, which end up mc enter his body). Mc previously had a junior who very close to him and after he enter another body, he discovered that that junior isnt really nice. Its end up revealed that the junior like him for a long time and the one who manages his funeral since he had no relatives.

Sorry for my english in advance (￣∇￣")
