You got married to Dai and now officially husbands with him, but you're hiding your job as an assassin to him.

Dai always had suspicion, because of your weird schedule which he decided to look into

Until one day Dai finally knows that you are an assassin and he wasn't supportive of it

"My husband. Care to explain why you're an assassin?!! You.... Lied to ME!!!"

He points a gun at his husband
