Haruta is a 40-year old former salaryman, who lost his job and wife when he snapped from overwork. He now works at a furniture shop, and lives on the bottom floor of his boss's house. He's sworn never to love again, but his life begins to change when he means a beautiful, but insane, stalker.

Haruta is now living under the same roof as his ex-wife, who's dating his boss, and sleeping in the same room as a stalker. His already fragile mind is ready to snap, and his ex is insisting that they not tell his boss they were married. Will he be able to hold it together?

Haruta gives up and is ready to go, but his boss stops him. His boss is weirdly positive, and visiting a psychiatrist to discuss the fact that he's incapable of being upset, worrying, or doubting anybody. Meanwhile, Miyako finds out that Haruta and Shizuka are married. But before she can tell Shin, Haruta snaps and tells him first.

After their fight in the river, everyone comes home soaked. Miyako blames Haruta for leaving her alone. He says he won't leave her alone anymore, and she grabs him and hugs him. Badly shaken, the next morning he tries to go back to the mental health clinic, but Shizuka is already there before he arrives.

Haruta and Miyako run off after the events of last episode. Shin finds them and brings them home, and by the time they're back they're all laughing and having fun. They all get drunk, and during the night Shizuka grabs Haruta and forces him to cuddle with her. The next morning she remembers none of this.
