Things are getting worse day by day, and honestly Jeongguk doesn't really know how to deal with it. But everything changes when the confession letter appears in his locker one day.

Kim Junmyeon is a university student, albeit a cold and icy one, his heart frozen after some things happened in his past. Kim Jongdae is a freshman at Seoul University, developing an interest in his friend's cousin and deskmate Kim Junmyeon.   Will Jongdae thaw Junmyeon's frozen heart? What actually happened to Junmyeon all those years ago? When the coldness of winter and warmth of hot coffee clash, everything is possible.
