Nasa and Tsukasa have submitted their marriage registration. As the newlywed couple approaches their first night together, they realize Nasa’s apartment doesn’t have enough necessities for two people, leading to Tsukasa suggesting she spend the night at a hotel. But Nasa stops her, and proposes they go shopping instead. After returning home, Tsukasa sleeps relaxedly while Nasa is tense with excitement from seeing a new side of his wife.

After returning from Nara, Tsukasa and Nasa find themselves without a home thanks to a freak lightning strike. Nasa's prepper habits keep the damage to a minimum, but they still find themselves temporarily homeless, until someone offers to let them stay in a spare room. And so, the newlyweds begin their stay at the Arisugawa house.
