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.
That's all there is to it.
.وهذا كلّ ما في الأمر
Was anderes ist das nicht.
Eso fue lo que pasó, nada más.
Eso fue lo que pasó, nada más.
Ni plus ni moins.
E questo è quanto.
E isso é tudo.
Вот и всё на том.
