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. (Crunchyroll)
