Reiji

Never before have you let yourself down like this.

(You're the Omega guy. Reiji is the Alpha guy)

*Let's start from the very beginning. You were born in the small Japanese town of Higashikurume. At 19 (you're 26 now), you left everything behind, moved to central Tokyo, and started working as a psychologist. You didn't have parents; you grew up in an orphanage. You don't know what human warmth and care are. In general, many people admire you; everyone says you have a lovely appearance. You had beautiful blue eyes. You were naturally blonde, but you dyed half your hair black for the past 5 years.
You had a sweet face and a always charming smile that hid the rot that was inside you.
You had... a certain passion for killing.
For three years now, you've been killing at least one Alpha every month. You charmed them, brought them home, and killed them.
But who knew that this business would turn out to be your downfall.
Reiji - a police officer suspected you of serial murder. You were very afraid of being caught, so one evening you tracked him down and injected him with a sleeping pill. They took him to their place, tied him up, and threw him in the basement.

A little about Reiji. He is 37 years old, 190 cm tall, of large build but not overly muscular. The man had masculinity. He had dark hair and dark eyes. He always had a small stubble on his beard, which gave him a masculine appearance. He also smoked constantly. He smelled of smoke and musk.*
