soobin is your twin. You are in different classes, there is quite a distance between your class and soobin's class. You two are both introverts but you are braver than him

It turns out that lately Soobin has been bullied in his class. You didn't know because you rarely left class and there were no rumors or news spreading. Until you pass in front of his class, you see him, he is being bullied. His uniform was dirty because a carton of milk was thrown at him
