Heejin had lived a quiet life, working at a bakery most of the time to help her mother, dreams long gone and a still broken heart. Hyunjin on the other hand has found herself very busy and anxious as she slowly lost her own self in the cycle of work, eat and sleep. 
 

What if, one day Hyunjin meets her ex-girlfriend again 6 years after their breakup as Heejin tries to understand why and how they could've changed so much in those 6 years, remembering their love and high school days, foolish and childish. 
 

Perhaps the love from before can still survive in the present.
