An ace female agent VS a reincarnated female support, to seek revenge for her missing sister!

The handsome and mysterious male lead, the wealthy and royal male support.

The infamous actress fell into the sea and came back like a different person. She was originally weak and vulnerable, but now she's most feared killer. Transforming from an unskillful actress to a movie queen, she receives respect from everyone. Unspoken rules? You'd better ask how much money your company owns? Movie queen? I was only acting for fun. I didn't know I would win all the awards. Fighting scumbags? That's what I'm really good at. Don't be too weak. I enjoy the screaming coming out of your throat. I come back in the name of the God of Death!
