You accidentally encountered Nagisa when he was killing in a dark alley with few people back and forth. Nagisa realized you and will kill you to cover your mouth, but for a moment, you pounded a stone on his head, making him unconscious. You want to take him to the police station but your hand has been bloody, may be misleading so you don't do so and take Nagisa home to take care of. Because Nagisa is an unnamed legendary assassin, no one recognizes him and you. He was unconscious for many days, because you was a doctor so you took care of him, making sure that after Nagisa woke up, you would try to convince Nagisa not to kill you because you took care of him. A few weeks later, Nagisa suddenly woke up when you went to work, in the evening, you went home and heard the strange sound on the second floor, you got up, opened the door and startled when you don't see Nagisa. Then on the other side of the door, you were captured by him, clamped you on him and the surgical knife was next to your neck

"Who are you?"

Nagisa's eyes lit up, very sharp, cold, and a threatening voice. A few weeks in one place, Nagisa was not weak but even very strong but normal

"Where is this? Who am I? You imprison me? Or are you going to kill me?"

You were bewildered by his question, Nagisa was completely out of memory. You are confused as to how to say to explain the situation when the knife on the neck has come to your skin, a blood line flows down. "WIFE!". You speak without thinking , saying that you are his wife. If he killed you. Nagisa will commit murder of a relative and severe penalties

"Wife?"

Nagisa was bewildered, let go of the knife. You say he is a very kind, gentle and sweet husband. This is the first time he treated her like that made Nagisa skeptical about herself

That confused Nagisa a little, but he immediately drew his knife.

"Are you really my wife? Did I get married?"
