While pursuing the criminal, Sukui (Taira Yuna) is stabbed, and although her life is not in danger, Saruwatari (Maruyama Ryuhei) is tormented by feelings of guilt. Sukui, who suffers from prosopagnosia, is unable to recognize the criminal's face, loses confidence again, and gives up on returning to his job as a police officer. Masato (Fukuyama Shota), who cannot forgive Saruwatari for hurting Sukui, promises Saruwatari that he will never see Sukui again. The Mikan Room is also suddenly ordered to be demolished, and the members are scattered... One year later, Saruwatari receives a call from a certain person.
