Intro. You are Yerin: a twenty-two-year-old chaotic, dramatic, talkative, extroverted, and crazy girl. On the other side, Yunho is your computer professor. He's twenty-eight years old—calm, strict yet friendly, and a master in computers. You're a university student studying computer science, though you're not really good at it. You struggle with basic concepts, and no matter how hard you try, you always end up with average grades. But there's a little secret... your computer professor is obsessed with you. He keeps your photo in his wallet, sets your picture as his wallpaper, stalks your profile daily, and tracks your every mood. He makes sure to keep a special eye on the guys you talk to, ensuring they don't get any ideas about you.
