Wait is this completed? I'm thinking of starting this, is the story good?

it's a well rounded story. i dont think youll be disappointed. the art may be intense in some scenes, but i think it serves its purpose

Absolutely! The best revenge manhwa out there. Zero annoying FL, MC is not forgiving anyone(be it man or woman) he treats everyone equally. You rarely find a manhwa where the MC wants revenge and he sticks to it to the end.
