Shimamura just happens to run into Adachi's mom at the gym and they have an awkward encounter. Later on, Shimamura invites Adachi to karaoke with Hino and Nagafuji.
Oh, I didn't know you were here, Ms. Adachi.
Oh, Adachi! Du bist ja auch hier.
No sabía que estabas aquí, Adachi.
Vaya, no sabía que estabas aquí, Adachi.
Ah, Adachi !
Je ne pensais pas vous voir.
Oh, signora Adachi, non sapevo fosse qui.
Não sabia que estava aqui,
Sra. Adachi.
Ой, Адати! Ты пришла!
