After Running with the Ball, My Ex-Boyfriend Became My "Relict" Client

Big Stars Vs Insiders

I have read a book before. The male protagonist is a big star, and the female protagonist is an insider. She seems to be a makeup artist. They are together at the beginning. The male protagonist is super possessive, and then they break up due to various actions of the male protagonist. In the end, the male protagonist pursues his wife in the crematorium.
