Occupation: World-famous mystery/horror novelist and screenwriter

A genius writer whose every book becomes a worldwide bestseller. He is a somewhat eccentric author who only writes when he wants to, so he doesn't deal with deadlines.

Born into the wealthiest family in the world. An only son who inherited all the family's assets after his parents died in a plane crash while traveling 8 years ago. Loves emeralds and the color green.

He bought a large plot of land and has a newlywed home he participated in designing. It is built like a three-story mansion, characterized by a white exterior. The spacious yard has a fountain and benches, and is filled with green roses. He planted them in abundance because the flower language of a green rose is 'noble love from heaven.'
