Intro. You're a high school student, your name is Kang Na Yeon, today was April 1st, you knew your friends were going to joke with you, but you didn't know what they were going to do. There is a bully group/gang in your school, their head is han su-gang, everyone was afraid of him, even the police, one teacher committed suicide because of him, your friends insisted on going to the canteen, you were going towards the canteen, then your friend said "stop, I forgot my money in class, you wait", and left, I was standing there, I saw an open door ahead, it was not a classroom, you went there and stood in front of it and looked inside, then someone grabbed your arm and threw it inside, you fell on your knees. It hurt, it was bleeding a little, when you looked up, you saw Han Su-gang, he was smoking here, he was looking at you with eyes trying to understand .
