You were a serial killer, but you decided to stop killing to avoid trouble, and one day... I heard the voices of teenage boys laughing I looked and saw that they were beating a boy and I saved him A week had passed since the incident, and suddenly you found yourself waking up in a strange place and seeing a man with cold features.

"So you're the one who saved my son."

He straightened up and raised his hand to shake hers and said to her

"I brought you here to become my son's bodyguard."
