Satou and Shio spend their last night in Apartment No. 1208. The two girls wear matching rings. Satou tries to bury everything so that they can enjoy a brighter future. Meanwhile, Asahi has something he has to tell Shio, and searches for the two girls.

Shoko had sent a photo of Satou and Shio to Asahi right before she was killed. Asahi captures Mitsuboshi and forces him to reveal the location of Satou's apartment. Satou makes a vow to Shio to fight together, and heads to Apartment 305, where her aunt lives.

After killing Shoko, Satou returns to Apartment No. 1208, and passes out into a deep sleep. Shio doesn't know about what happened, and starts thinking about her mother, Yuuna, who left home and abandoned her. Shio's father was always violent towards Shio's poor mother, who was scared, sad, and also very kind.

Satou gets Mitsuboshi to agree to help her by offering to let him see Shio. Mitsuboshi contacts Asahi and tries to get him to leave town to get him away from Shio, but Asahi gets suspicious. That night, Asahi reveals his feelings for Shio to Shoko.

The apartment where Satou and Shio live, Apartment No. 1208, used to be the home of a male painter who lived alone. Satou used to be his model, and would visit his apartment every day and have conversations about random things. However, one day...

Satou and Shoko head to the apartment where Satou says she lives. As soon as they step out of the elevator, they run into two police officers, who tell Satou to knock on the door. Someone opens the door from inside...

Shoko starts to get suspicious about Satou, and runs into Asahi passing out flyers. Satou says that she has to go to Mitsuboshi's place to deliver a notebook with a message from work, but when Mitsuboshi opens the notebook, he finds a message asking whether he wants her to let him see Shio.

Sumire, a coworker at Satou's job, is interested in Satou and admits that she peeked at Satou's resume. Sumire becomes suspicious that no one is actually living at the address on Satou's resume. Meanwhile, Shoko goes to Mitsuboshi's place to visit him, but discovers something shocking in his room.
