Based on the conversation on the show, the two of them have a sleepover at Chika's fancy house. Yumiko's happy to see Chika enjoy the dinner she cooked. Then for some reason, they end up taking a bath together. How did it come to this?!
Y-You poked my side!
!لقذ لكزتِ جانبي
W-Was stichst du mir in die Seite?
Das ist unangenehm.
¡Me has pinchado! Qué asco.
Me toucher la taille comme ça…
Perverse, va !
V-Você cutucou minha costela!
Не тыкай меня под рёбра, извращенка!
