Kokoro ga Pokitto ne

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.

The whole gang goes clam-hunting on the beach. Haruta gets drunk and starts raving at everyone, screaming at his ex-wife Shizuka and the new girl he loves. Shin admits that he doesn't know if he loves Shizuka as much as he loves Miyako as well. The girls get angry and banish the boys to the first floor.

Haruta wakes up after his drunken rampage to find that the boss has moved in with him, and Miyako and Shizuka are living on the top floor. He has no idea what happened, and is appalled when he finds out. A while later, he encounters an old co-worker of his, whose life he ruined before he had his mental breakdown.

Ryou and Kanako have a drunken one-night stand, (or so he thinks), and Ryou is uncertain of what to do. He goes to Shin for advice, and Shin gives him the best advice he can: Ryou needs to marry Kanako, despite the fact that she's decades older than he is.

Shizuka has a big book deal! A publishing company wants her to author a book on weddings. With success in her grasp, all she has to do is find a married couple. But when her first choice backs out, her only option is to get married herself!

It's the day of the wedding, but Shin has disappeared! Shizuka's book deal is off, and she doesn't know if she'll even be able to get married at all. Haruta tries his best to comfort her, but it's no use. Will they be able to find Shin in time?
