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.
It must be because of 
your chocolate, Mayu-chan.
لا بدّ وأن الفضل يعزو لشوكولاتتك يا مايو-تشان
Das muss an deiner Schokolade
gelegen haben, Mayu-chan.
Fue gracias a tus chocolates.
Fue gracias a tu chocolate.
C’est sûrement
grâce à tes chocolats.
E credo che sia tutto merito 
dei tuoi cioccolatini, Mayu-chan.
Deve ser por causa do seu
 chocolate, Mayu-chan!
Всё благодаря твоему шоколаду, Маю.
