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.
Don't call me Big Sis in class, okay?
In der Schule darfst du mich aber
nicht große Schwester nennen.
No me digas “hermana mayor”
en clases, ¿sí?
No me llames "hermana" en clase, ¿vale?
Ne va pas m’appeler
« ma sœur chérie » en classe.
Ma non chiamarmi sorellona in classe, okay?
Não me chame de "irmãzona"
na sala, certo?
Только не надо звать меня
старшей сестрой в школе.
