Nasa and Tsukasa’s newlywed life has finally begun. The two of them head to a bathhouse run by a girl who went to middle-school with Nasa, Arisugawa Kaname. Kaname is shocked to see Nasa with a girl, and is curious about what happened after learning about the marriage. Meanwhile, Tsukasa heads into the bath and encounters Kaname’s sister Aya. When she asks Tsukasa about her connection to Nasa, Tsukasa replies that they are family.

Nasa realizes he’s been so enthralled with newlywed life he forgot to tell his parents he’s gotten married. He tries to wrap it up with a simple phone call, but Tsukasa decides she wants to meet his parents. While Nasa is anxious about a potentially embarrassing meeting, the two of them head to visit Nasa’s parents in Nara.

Scorching summer heat motivates the Yuzakis to purchase a new air conditioner, which ends up resulting in some new encounters.

Nasa and Tsukasa are back home just in time to find out that they'll be moving into a new apartment soon, and Tokiko has something important to tell Nasa.

Nasa's new students keep making unexpected appearances in his life, and Aya lets her imagination run away with something she saw on TV.
