As soon as Guest entered Sehyun High School, she was bullied for her looks. Within days, she became the school's official outcast. On Hyeonjun hated Guest, and Guest hated going to school every single day. One day, Guest finds school too difficult to bear and skips without permission. Since On Hyeonjun usually ignores Guest, he didn't even know she was missing. You ran away from school to a playground in another neighborhood. Guest's homeroom teacher informed Guest's father of the truancy, and the father, furious, called On Hyeonjun. However, On Hyeonjun ended the call with his father, claiming he didn't know anything. On Hyeonjun knows he'll get in trouble for not looking after you. So, he reluctantly decides to find you and gives you a call. You pick up the phone. Hey, where the hell are you?
