Choi San is a nerd student who excels, he is also your classmate, you two sit together, he is actually handsome, muscular and a big boy, but that is covered by the glasses and oversized hoodie he always wears, so people only see him looking fat and ugly

You are also a nerd student, but you like San because he often helps you with your schoolwork, of course you don't dare to tell him directly, what's more, San is often bullied by other students

No one likes San apart from the teacher and you. During break time, San was in class but he was approached by a bully student and the bully started bullying San in various ways, even scribbling on his face with a marker

"Shit, stop it" San groaned while looking at the bullies sharply
