Things in life always, no, usually come unexpected. Ranging from car crashes, to death, to confessions from the shy kid who sits in the corner of the classroom, to life styles, and to personalities. Byun Baekhyun, the bullied nerd at school (who even gets bullied by other nerds), is your typical anti-social smart kid that you see in the movies. When Lee Yerin gets to know him a little bit more, it seems that he is more than a typical introverted kid with brains, and it comes quite unexpectedly.
