   One winter day, Tae-hyeon (Jeong Seong-yoon) and Chae-ri (Lee Yu-ri), dressed in school uniforms, run into the university admissions announcement room, breathing heavily. Chae-ri, who was preoccupied only with checking her own acceptance, asks Tae-hyeon about her passing as if she had suddenly remembered. Tae-hyeon says that no matter how much he looks for his name, he says he prefers that Chae-ri passed. For Tae-hyeon, who gave her a present for Chae-ri, who is going to Seoul tomorrow, Chae-ri says she will grant her wish, saying just say anything. However, Taehyung is only shy and he cannot tell his wish. Chaeri, who is on the train to Seoul, asks to meet her at her school next year. Tae-hyun, who entered a spartan-style retraining academy to meet Chae-ri, devotes himself to studying with Sang-hyeok (Moon Ji-yoon). Meanwhile, Cheri joins a hang gliding circle with Suyeong (Shoo) and meets Jun (Gong Yoo) there... .
