Hinako is too cold to fall asleep, so she heads downstairs for a warm drink and notices a tasty smell coming from the coffee shop. Curiously, she peeks into the dark kitchen... and sees Mayuki stirring something in a large pot, chanting Chiaki's name like some sort of spell. Hinako timidly speaks up, and Mayuki's reaction makes it appear that she's hiding something. Unable to bring herself to question this strange behavior further, Hinako tells Kuina about what she saw.
I think it had more to do with how you and 
Hina-chan looked in the maid outfits.
أعتقد أن الفضل يعزو أكثر لثياب
الخادمة الذي ارتديتِه أنتِ وهينا-تشان
Ich glaub, das lag eher an deinem
und Hina-chans Dienstmädchen-Outfit.
Que ustedes fueran vestidas
de sirvienta seguro que ayudó.
Que vosotras fuerais vestidas
de sirvienta seguro que ayudó.
C’est aussi grâce à vos vêtements
de soubrette, non ?
Secondo me grosso del merito va a quanto 
eravate belle tu e Hina-chan vestite da cameriere!
Eu acho que é graças a como a
 Hina-chan fica de empregada.
А мне кажется, дело 
в ваших с Хиной нарядах.
