Six university students have made the final round for recruitment at company Spirallinks. The candidates are Iori Shima, Shougo Hatano, Souta Kuga, Tsubasa Yashiro, Kimihiko Morikubo, and Ryou Hakamada. For the final round, they are tasked to form a team and hold a group discussion in one month. The group deepens their relationship with each other so they can each receive a job offer, but, right before the group discussion is to be held in a conference room, they are informed of a change that has been made. The change is that the job offer is for only one person and that person will be selected by their group. The six hopeful applicants suddenly become rivals with each other as they vie for the only job available. They then find six envelopes left for them. When the envelopes are opened consecutively, their lies and sins are disclosed. Eight years after the group discussion that turned into a nightmare, a letter arrives at Spirallinks.
