World's Greatest (COTE x Male Reader)

One day a new student who showed up a month late to school. His name is Y/N L. L/N, he is very interesting but something seems weird. He is different from everyone, yet seems the smartest. How will he vary against everyone? And who truly is Y/N L/N? And can he bring class D to class A?
