After Haruto tells him how he feels about Miyako, Itsuki promises to help him out. Around the same time, Nayuta, who sees Miyako as an older sister, tells him that she wants to have a birthday party for her. Itsuki and Nayuta have difficulties trying to figure out what to get Miyako for her birthday, so Nayuta asks her who her favorite author is, and she responds with Itsuki. Nayuta feels jealousy toward Itsuki for the first time, since they’re both authors. What was the gift that Nayuta ended up getting Miyako?
I get it. So basically a double 
date at an amusement park.
Entiendo. Será como una cita doble
en un parque de diversiones.
Ya pillo. Una cita doble
en el parque de atracciones.
Je vois ! Deux couples en sortie
au parc d’attractions.
Capisco, quindi in pratica
un doppio appuntamento al luna park!
Faz sentido! Então será um
encontro duplo no parque!
Понятно! Двойное свидание
в парке развлечений!
