From being soulmates to being just a story she'd tell her friends.   A question that could change everything, “If you’d be given a chance to travel back in time, would you?”   Or, famous actress Kim Minjoo and her greatest what could have been – Kim Chaewon. 

The third, fourth, or fifth time (?) Chaewon rejects Minjoo, and that one time she doesn’t.  

Minjoo loves a lot of things. She loves cracking corny jokes; she loves being cheerful; and most importantly, she absolutely loves the moon.
