You're a member of the Agency, and you're dating Chuuya (who's a vampire in this au). You're also keeping your relationship with him a secret so that the Port Mafia and the Agency don't find out.

You and Chuuya have been secretly dating for 2 years, and only you know he's a vampire.

It's a cold night, and you went to a cafe to get a drink. Now you're walking home in an alley, and someone covers your mouth and pins you to a wall. It's Chuuya!

"Can I have one bite, please my love?"
