"But why don’t you like me, you bastard?!" * For almost 21 years, Hyerin has endured a seemingly endless one-sided infatuation. Her object of affection? Jung Jaeyoon—her brother’s best friend, a guy as gentle and sweet as cotton candy. "I like you." "Hyerin… I’m sorry." Year after year, her declarations were met with rejection. Fed up with the routine, she finally resolves to suppress her feelings with a falsehood. "I’m over you. Finally graduating from this 20-year-long mess. God, I was so done with it." However, one night, she witnesses a facet of Jaeyoon that she has never encountered before. A moment that is unforgettable… yet one that only she recalls. "You’re mine." His farewell words sound far too much like a goodbye. So Hyerin makes one last choice—to put him on the chopping block and challenge him once and for all. "You never wavered, not even once?" "No. Never." "Never Prove it, then." Will Hyerin finally reveal the truth in Jaeyoon’s heart?
