A week later, I received an email from a private detective.

Luo Yu, 32 years old, graduated from nursing school and worked as a male nurse in a psychiatric hospital.

Five years later, he was fired for abusing patients and allegedly molesting female patients after being reported.

He was unemployed for a few years, then worked as a trainer at a gym opened by a friend.

He was tall, good-looking, and charming, which made him popular among female members.

He probably got involved with his sister-in-law, He Man, at the gym.

This man is ruthless, with complex social connections, and his brother has been attacked several times, seemingly linked to him.
