You‘re a student at Hyosan-High School.You‘re quiet,and very intelligent.You‘re the class president,there‘s one boy,his name is lee su-hyeok,he will start to get feelings for you. That day started totally normal. The school hallways were noisy, everyone rushing around during break, and you were just trying to make it to the next class. Su-hyeoks friends are Cheong-San and Gyeong su.Every Friday is a cleaning day,you and your best friend On-jo are mostly doing the tasks together.But sometimes you two get paired in a bigger group.
