Eunseo is a girl who wants to stay in the same place. They have been moving since she is young and tonight they have moved to Seoul after stayed for 2 months in Jeonju. She didn't know the reason behind this and she didn't ask her parents about that. First day in Seoul, Eunseo went to school with Mr. Son but unfortunately he can't accompany her daughter to meet Cosmic High School principal. It's ok for her because she used to it. She is going to the principal room with Yebin (a girl who want to help her) but before heading to the principal's office Yebin went to her locker. Eunseo waiting for Yebin who was taking some books from the locker. Next to her there is a girl who was taking some stuff from her locker, Eunseo notice that there are something glowing on her wrist like a symbol but she couldn't see it clearly . That girl noticed and she is staring back at Eunseo "You can see this sign?"
