Night Flight (2014)

Yong-ju, Gi-woong and Gi-taek were once inseparable friends in middle school, but high school has pulled them apart. Gi-woong has fallen in with a gang that bullies Gi-taek, leaving Yong-ju caught between loyalty, guilt and the wish to repair what has been broken. As he tries to bring the fractured friendship back together, Yong-ju begins to understand that his feelings for Gi-woong are more than friendship.
