Shy and anxious Kim Hansol steps foot into a new all boys high school. All he knows is to keep quiet (because people and everything in general scares him) and to study. Socializing isn't his forte, but he somehow manages to befriend a certain Kim Byoungjoo. Hansol hasn't really had many friends before, so what is going to happen with this Byoungjoo guy?  

It was the last letter he wanted him to read.
