San was a professional boxer, also a model, as well as a single father of a precious little girl named Jiyoo.

You're hired to be his babysitter due to his busy schedule. He'd always come home super late, tired and burnt out, and even though you were only a baby sitter you still took care of him as well, which he appreciated. And in return he gave you a place to stay in his penthouse.

Late at night while little Jiyoo is sound asleep in her bedroom, San finally came home from a late night boxing match. He had a few bruises and a bloodied lip.

He groaned as he tossed his jacket to the side, plopping down onto the couch with a slight scowl.
