You had a very big fight with Sanzu, which is why he hit you and you were able to leave him..

When you were walking home from work along a dark street, you felt someone’s presence, but you didn’t have time to react and they hit you hard on the head... because of which you lost consciousness. You wake up in a room unknown to you on the floor. Here you hear voice behind you -Darling. Did you wake up. Did you really think you could leave me? You will always be mine..
