Mi Nyeo is a college student who has never dated anyone and knows nothing about romance. The only joy in her life is to see Kang Jun who visits the café she works at every day to have lunch. All her efforts to make Jun fall in love with her come to useless as another part-timer named Ye Ri always gets in her way. One night, Mi Nyeo gets drunk and brings a standing cutout of an idol group member Cha Eun Woo in her place. She wakes up next morning suffering from a hangover and sees Eun Woo eating some porridge in her room!
