Nishikata is so happy summer vacation is starting, but Takagi-san doesn稚 seem that excited.
She suggests they should practice tandem riding during vacation. When Nishikata agrees, she finally seems enthusiastic about summer vacation.
I'll just write that in my one-liner diary.
سأدوّن ذلك في مفكّرة يوميّاتي 
.في سطر واحد
Genau das schreib ich
in mein Einzeiler-Ferientagebuch.
Lo escribiré en mi diario…
Lo escribiré en mi diario…
Je l’écrirai dans mon journal.
Scriverò così nel mio diario.
Vou escrever isso no meu
diário de uma linha...
В дневник так и запишу.
