Nerd By Morning, Prince By Night
He is a nerd who doesn't have any friends. Only stick with the book every second. What they didn't know is, the mask will disappear during night, change by something unthinkable. In the morning, he goes by the name 'Kyungsoo the Nerd' but at night, he goes by the name 'D.O the Prince'. No one seems to know that Kyungsoo and D.O is the same person. What will happen when the school Kingka, Kim Jongin aka Kai, saw D.O and fall in love with him?
Oh, and by the way, Kai doesn't know that D.O is Kyungsoo.
