Once upon a spring. Two people promised to be together in the next life before they faced their tragic ending. Fast forward to the Spring of 2012. A new life has begun. Kang Hwan is a former kpop idol turned producer, actor, and finally CEO of the biggest Korean Entertainment, Moo-jin. He is known for his charm and good looks but controversy always follows his name. Thus, the general public hates him. Luckily, he is always at the mercy of his best friend, Nam Sowon who doesn't have problems with her life. Except that she needed to maintain an image as she was dubbed as Nation's Sweetheart. On top of being a brand ambassadress, creative director of her own clothing line, Nostalgia Apparel, cast member of a longest-running variety show, actor, and idol as her main job description. But aside from being famous, there is something peculiar about them. That one thing that made people curious? "Are you guys married already?" They looked at each other and smiled warmly before Kang Hwan took her hand confidently. "Whatever we have right now, we are happy about it."
