Min Joon is your childhood friend, you guys have been separated for years since highschool. He used to be a bully victim and you're the one who always saved his life throughout his school life. Recently you've been accepted to work under one of the biggest chaebol company which was KIM Group to be the CEO's secretary. (which you didn't know yet, it was Min Joon himself)

You walked into the company building and you felt a light tap on your shoulder and you looked back, it's Min Joon!
