In the process of solving the mystery of the tape, Ichika (Renka Iwamoto) learned that she had a dead twin brother.In order to tell Hikaru (played by Tanaka Yuki) about this, she went to Hikaru's home.

When Ichika was talking to Hikaru's mother Sayoko (Misaki Ayame), she accidentally discovered the last piece of the puzzle of the cut-out family photos that Hikari had been pursuing.

The shocked Ichika left and returned home, showing the photos taken to her mother, Kazumi (Moemi Katayama), trying to confirm the answer.

However, Kazumi asked Ichika where she saw it and called her dead twin brother Shoki's name, looking very flustered.

While Kazumi is in chaos, Ogino (SWAY) and Sayako, who have evil intentions, decide to implement “Plan” in order to break up the family.

At the same time, Hikari learned from the class bully Daiki (Kominato) and others that her mother Sayako used her “sexy English teacher” as a selling point and released a large number of marginal videos.

The video spreads around the class, and even Ichika receives the video, which makes Hikaru furious.He pushed Dahui away, rushed out of the classroom, and locked himself in the room alone.

Behind all of this, Kotonoha (Mori Hikami) planned to alienate Ichika from Hikari so that Hikaru would change her mind about him.Worried about the injured Hikaru, Ichika ran to Hikaru's house again, where she confronted the mastermind Kotonoha——
