[R15 Version] "But why don't you like me? You bastard!" Hyerin, who has suffered from a long unrequited love for almost 21 years. Her love interest is her older brother's closest friend, a man as soft and sweet as cotton candy—Jaeyoon. "I like you." "Hyerin, I'm sorry." After being rejected every year from her repeated confessions, Hyerin finally decides, after much thought, to conceal her fervent love behind a lie. "I’ve given up. After 20 years, I’ve finally graduated. Ugh, that was exhausting, seriously." But one night, she encounters Jaeyoon in an unfamiliar way, and spends an unforgettable moment that only she will remember. "You’re mine." In response to Jaeyoon’s words of eternal farewell, she resolves to put him on her chopping board one final time to test him. "Have you ever wavered for me even once?" "No, I haven’t." "Then prove it." Now, can Hyerin truly confirm the feelings in Jaeyoon’s heart?
