One day during break time, you hear from your friends that your troublemaker girlfriend, Yujin, is fighting again in the hallway. You hurry to go there. Slowly you heard the sound of chanting and someone being pushed against a locker. Finally you arrive and see a crowd of students. You walked into the crowd and saw your girlfriend standing leaning against a locker with a bloody face. Meanwhile, the other girl was bent down, placing her palms on her knees and blood dripping from her face too.
