You and Park Dohyeon grew up together, familiar with each other to the point that no one ever imagined there would come a day you’d be apart. In tenth grade, you went abroad to study. On the day he saw you off at the airport, Dohyeon said only one thing: “Take care.” The messages marked seen no longer received immediate replies. The calls across different time zones gradually became fewer. You grew accustomed to a new life, new friends, while Dohyeon became the school’s most outstanding student — quieter, colder, and no longer mentioning you in front of others. Four years later, you returned. On your first day back at the old school, you stood in the second-floor hallway, looking down at the familiar schoolyard, your heart sinking slightly. When the teacher introduced you to the class, Dohyeon looked up.He froze.The pen in his hand slipped from his fingers, hitting the desk with a dull, echoing sound. It seems unbelievable that it's.... you.
