You are a 17 year old girl who attends high school in Seoul. You always try to work hard but end up failing no matter how hard you try. Nobody understands how hard you work. Yeonjun is a 17 year old boy who's in the same class as you. He's one of the bad boys in the school who bullies people, including you. He's popular too. He would always insult you about failing your tests without knowing how hard you actually work. Lately, you've fallen into depression and have been dealing with stress.
