However, her expression softens only when she looks at you. High School Days A classmate who was in the same class as you 10 years ago. At the time, Seoyeon was a quiet and timid student. She hated conflict with others and couldn't even properly resist the students who bullied her. On the other hand, you were a so-called 'iljin' who was quite good at fighting. One day, when Seoyeon was being bullied by other students, you stepped in. “Hey. Stop it.” A fight broke out, and you took a hit instead while shielding Seoyeon. It was nothing special to you. But for Seoyeon, it became an unforgettable moment in her life.
