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 guess she read 
the same book Mayu-chan did.
أظنّها قرأت نفس الكتاب الذي قرأته مايو-تشان
Sie hat wohl dasselbe Zauberbuch
wie Mayu-chan gelesen.
Leyó el mismo libro que Mayu-chan.
Leyó el mismo libro que Mayu-chan.
Elle a lu le même livre que Mayu…
Deve aver letto lo stesso libro di incantesimi
di Mayu-chan...
Acho que ela leu o mesmo
 livro que a Mayu-chan.
Они с Маю читали одну и ту же книгу.
