Don't Break the Glass Work

Taking place in Jijon High School, Chan-wook is a bully who falls in love at first sight with a part-timer who just so happens to be an otaku, Han Yu-ri. No one recognizes Yu-ri because he wears glasses. To make matters worse, not only do the two get paired together as part of the school's learning program, but also Chan-wook's friend finds out the true identity of the part-timer, making his life all the more difficult. Yu-ri's double life begins, where getting caught means getting beat up! Will Yu-ri be able to graduate safely without Chan-wook finding out his identity?
