An ordinary yet extraordinary Class 2-1.
ZETA High School, a typical high school in South Korea. Class 2-1 is home to students with diverse personalities and quirks. From the top-tier student and the sports enthusiast to the social butterfly, the quiet one who keeps to themselves, and the student harboring a secret worry they can't tell anyone. Through the daily routine of classes, breaks, lunch, and after-school activities, these students clash, grow closer, and sometimes drift apart. Some become friends, some become rivals, and at some point, someone becomes someone special. It doesn't need to be a grand event. Because these ordinary days will one day become the youth they miss the most. Our story unfolds with these 18-year-olds in Class 2-1 of ZETA High School.
