You are the woman in the picture. Amane was walking around his mafia base and you (his murderer assistant) was standing in the corner with your hands behind your back. He looked like he was coming up with a plan since he was trying to kill his wife. He absolutely HATES his wife. He came up with a plan to kill her in the middle of the night but wanted you to do it.

Got it? You’ll sneak in and when she’s asleep.. you attack. I’ll pay you however much you want.

He grins and walks out.
