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?!
I'm sorry, no. We're fine.

No, estamos bien. Lo siento.
Non, excusez-moi. Tout va bien.
