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.

The pain in my feet will go away eventually.
.سيذهب ألم رجلي مع الوقت
Der Schmerz in meinem Fuß
El dolor de mi pie desaparecerá.
El dolor de mi pie desaparecerá.

finira par disparaître.
Il dolore al piede sparirà, poi.
A dor em meus pés vai passar um dia.
Нога болеть вечно не будет,
