The day after the school festival ends, second-year Class Two holds a Christmas party to celebrate a job well done. While the festivities are in full swing, Tomozaki happens to notice Hinami and Kikuchi having a conversation. But when the two try to play it off as nothing, Tomozaki gets awfully curious... This short story collection provides a glimpse at the characters' lives and choices through the years: the birth of NONAME, Mimimi and Kikuchi's chat in a cafe, a karaoke party, Rena's life before she met Tomozaki...and much more!
