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.
So yesterday... My mom was being weird.
Meine Mutter war gestern
irgendwie komisch drauf.
Así que ayer… mi mamá se portó rara.
¿Sabes qué? Ayer mi madre estaba rara.
Au fait, hier…
Ma mère était bizarre.
Ma ieri...mia mamma era strana.
Ontem, a minha mãe estava estranha.
Знаешь, вчера… мама вела себя странно.
