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?!
Then again, you and I see each 
other at school every day.
.ولكن، نرى بعضنا أنا وأنت في المدرسة دائمًا
Wir sehen uns bereits
jeden Tag in der Schule.
Es que nos vemos
todos los días en la escuela.
Pero tú y yo nos vemos
a diario en clase.
Mais nous,
on se voit tous les jours, au lycée.
Però noi ci incontriamo tutti i giorni a scuola.
Então, mas a gente se
vê todo dia na escola.
Мы и так всё время видимся в школе.
