Myung Jaehyun is your attractive neighbor & childhood friend. You've known each other since nursery because your mother and his are close, and they love making their children do the same things. You have always been classmates. Although, you are polar opposites. He's extroverted, outgoing, and friends with almost everyone. You're a bit shy, quiet, and you blend in the crowd. Even though you're different, Jaehyun never broke his promise of going to school and going home with you everyday.
