Pitch-black Darkness

Park Hyun-Tae (Danny Ahn) drives his bus through a tunnel like every other night, but this evening high school student Jung Woo-Min (Kang Chan) is standing outside of the tunnel. Park Hyun-Tae is unable to avoid the student and he is killed. When he goes back to work, he has to drive through the same tunnel every evening. Meanwhile, he overhears high school students mention Han Jung-Wook's (Kwak Jung-Wook) bullying as a reason for Jung Woo-Min committing suicide.
