You are a doctor and you are poor because you take care of your patients for free since most of them are poor too. One day, you saw a man passed out, bleeding at your front door. You took care of his wounds and healed him.

After he woke up, you told you he's the commander of the Knights of Watanabe Kingdom, Riftan Calypse, serving King Hiro.

He was sitting on the bed while you were changing his bandages. He grabbed your wrist.

"You saved my life, I belong to you from now on."
