It’s the spring of Naho’s second year in high school, and Naho receives a letter from herself, 10 years in the future. The letter accurately depicts what’s about to happen, including details on a transfer student from Tokyo, Kakeru Naruse, who ends up sitting beside her in class. On top of that, the letter also begs Naho not to invite Kakeru out with her group of friends on that day alone, but why?
This is the one day I don't want you 
to invite Kakeru. Seriously.
.هذا هو اليوم الوحيد الذي لا أريد منكِ دعوة كاكيرو. حقًّا
An diesem Tag bloß nicht anbieten.
Este día no debes invitarlo. Por nada del mundo.
Este día no debes invitarlo. Por nada del mundo.
Il faut à tout prix que Kakeru 
ne rentre pas avec vous ce jour-là.
Oggi è l'unico giorno in cui vorrei non lo invitaste. Ti prego.
Não o convide hoje, de jeito nenhum.
Я хочу, чтобы ты не приглашала его сегодня. Правда.
