After a devasting car accident leads to two of the member's disappearances and the group's disbanding, ex-group leader Bang Yongguk finds himself looking at the download page of a mysterious game named Psychomachy and can't help but click as his mouse hovers over the download button. It doesn't take long for Yongguk to realize the game is more than just a simple fangame when it starts to play through his life. The game is his only chance to find out what happened to the two members that mysteriously went missing the day of the accident, and he can only save one. Yongguk only has one chance, if he runs out of time its game over.
