Nasa and Tsukasa are now enjoying newlywed life as guests of the Arisugawa family. Things proceed normally until they receive a call from Nasa's previous landlord, offering them an apartment at a newly constructed building. The two of them go to check out a showroom of their potential new home, arriving at a high-rise apartment building.
If we were a high school couple,
لو كنّا زوجًا في الثانوية
Wären wir beide bloß
ein Oberschülerpärchen,
Si fuéramos estudiantes,
Si fuéramos estudiantes,
Si on était un couple de lycéens,
Se fossimo una coppia delle superiori
Se fôssemos um casal de
estudantes do ensino médio,
Будь мы старшеклассниками, беспокоились бы, 
что родители ждут у дверей.
