Kai goes to the bookstore to buy the new volume of "Forward World." When he gets there, he sees Ryo and immediately tries to avoid him. He remembers what Rio said about her brother to him and feels a little down, but when he goes in to grab one of the copies of the new volume, his hand touches Ryo's hand. Meanwhile, Arie manages to secure the new volume at another store and she runs into Ichika. They realize they have the same favorite character and end up bonding. On her way home, Arie is thinking of Ryo and she realizes something.
He asked me not to tell anyone, so he 
probably hasn't told Rio-chan, either.
.طلب منّي ألاّ أخبر أحدًّا، فلعلّه لم يخبرها أيضًا
Da ich es nicht weitersagen sollte,
glaube ich nicht, dass sie es weiß.
Me pidió que no le contara a nadie,
así que no creo que le haya dicho.
Me pidió que no se lo dijera a nadie,
así que no creo que lo haya contado.
Ryô m’a demandé
de garder le secret,
Mi ha chiesto di non dirlo a nessuno,
 quindi probabilmente neanche Rio lo sa.
Ele me proibiu de dizer, então acho
que ele não contou para a Rio-chan.
Рё попросил меня никому об этом 
не говорить, так что вряд ли он сказал Рио.
