Nana and Nobu, along with Hachi, start their search for two more band members. Meanwhile, Shoji is asked to train a young girl named Sachiko. Hachi previously joked about Shoji having an affair with a woman named Sachiko, but this is just a coincidence, right?

Hachi finds a new job but is not enjoying it at all. Nana's band finally get an opening to play. To celebrate, they go to the family restaurant where Shoji and Sachiko work. This spells trouble for everyone involved.

Nana and Hachi travel back to her hometown to see Trapnest perform. While there, Hachi learns a few things about Nana she didn't know before, including her feelings for Ren now.

The last day of Trapnest's tour is here. Hachi wonders if Takumi will come to see her now that the tour is over. Nobu and Shin join Trapnest at the after party, where a confrontation emerges.

Nana goes to live with Ren for the two weeks that Trapnest have off. Reira and Takumi visit America and bump into each other there. Nobu walks Hachi home but Takumi turns up and walks her the rest of the way. Hachi avoids going to watch BLAST practice because she can't face Nobu and Misato comes to visit for summer vacation.

Hachi feels ill during work and her boss tells her to see a doctor. Nobu gets Nana a job at the moving company he part-time works for so she can make some money. Hachi makes a shocking discovery.

Takumi and Hachi tell of their decision to marry. The other Trapnest and Nana are shocked by this. Nana is so upset she drops the Strawberry Glass they bought together back when they first moved in.

Shouji, Junko and Kyosuke discuss the possibility that Hachi's fiance is Takumi from Trapnest. Meanwhile Hachi meets Naoki for the first time and shows off her new apartment to him and Takumi. Takumi tells Hachi that she doesn't have to keep their relationship a secret from their friends and family and expresses his desire to go and meet with Hachi's parents and sisters.

As both bands rehearse for a TV appearance, Yasu confronts Ren about his drug use and treatment of Nana. Ren later proposes to Nana, followed up by a session of rough sex which excites and terrifies Nana at the same time. Reira and Shin manage to sneak out for some alone time, while Nobu is discouraged when he learns that Miyu is seven years older than him.
