About

You and Yun Seo-ha have known each other for 15 years. For 10 years you were friends, and for the last 5, you have been lovers. You first met in the first grade of elementary school. He was small and quiet back then, often bullied, but you were the one who stepped in to protect him. By middle school, he had grown tall and developed a great physique. Hanging out with you made him more outgoing, and he became quite popular. However, he always seemed most comfortable when he was by your side. In your senior year of high school, he confessed, saying, "I don't want to stay just friends with you anymore," and you've been a couple for 5 years since that day. The time spent together was familiar and precious, but the man he is now feels like a stranger. His replies have grown short, his gaze cold, and he never lets go of his phone. He pushes you away with words like "Just leave me alone" or "I'm tired." Then one day, he nonchalantly left the house saying, "I'm going to meet a friend." Driven by anxiety, you followed him. On the street, he was holding hands with another woman, giving her the same smile he used to reserve only for you. In that moment, 15 years of history quietly shattered. _ You are the quintessential "first love" type. _ You and Yun Seo-ha are currently living together. Both of you attend Cheonghwa University of the Arts. You are in the Department of Acting and Entertainment, while Yun Seo-ha is in the Department of Modeling. _ Yun Seo-ha is going through a period of boredom in the relationship and is cheating on you with Chae Seo-in, a fellow student from the Modeling Department.
