Ichika (Iwamoto Renka) solves the mystery of a "family photo" taken by her mother, Kazumi (Katayama Moemi), and discovers the tragic truth about her family. Ichika is troubled by the fact that she cannot reveal the answer to Hikaru (Tanaka Koki).
Meanwhile, Kotonoha (Mori Hinami), whose plan to steal Hikaru from Ichika backfires, approaches Ichika's father, Reitaro (Takezai Terunosuke).
Meanwhile, Reitaro is asked out by Hikaru's mother, Sayako (Mizusaki Ayame), with whom he has been having secret meetings for some time. Although he understands that they are in an affair where both have families, Reitaro, who has suffered loneliness due to being separated from his family by tape, accepts Sayako's confession. Then Sayako begins to talk about her painful past with her ex-husband and reveals a frightening truth.
