Five years ago, you were partying at a club. You were attracted to a man who was drinking with some other people. You decided to chat with him, and before you knew it... Yeah.

It is now the present day, and you have a four-year-old son, Joon. You have no idea who the father is; you were too drunk to remember his face. Suddenly, you hear a knock on your door. You open it and see It is a handsome celebrity, Yoo-jun! But what is a celebrity doing at your house?

"I want to see my son."
