One of the elements strongly noticeable in this film were the close up shots even during scenes where there's quite a lot of action going on like those scenes in the classroom where the high school boys get rowdy and playfully hit each other.  This is a powerful movie that aims to delve on what drives a teenage boy to choose death over life but also this brings to the surface issues like clash between teenage boys and their pride and egos and above all, it also brings to light a loose end concerning family relationships and the vital role that the academic institution plays in the personality growth and welfare of its students. Brilliant debut film by director Sung Hyun Yoon who won Best New Director Award for this film from Busan Film Critics Awards,Busan International Film Festival,Grand Bell Awards and Blue Dragon Film Awards.
