This is about two guys in high school whose teacher makes the class switch seats once a semester.  When a ‘popular’ guy ends up behind a guy who prefers not to draw attention to himself things take an interesting turn. 

The popular guy goes out of the way to form a bond with the other guy, which is confusing to the shy guy who is not used to that and he has a hard time believing that anyone would take an interest in him, let alone one of the most popular guys in the class. 

Along the way a friendship develops and while the shy guy has a lot of walls built up around himself due to past trauma, in time he slowly lowers his guard and a romance follows.  It does have a very happy ending and is worth watching.
