“Hiroto-kun, take me as your wife when we grow up!” “Yeah! All right! I’ll protect you, Haruka!” Two people born and raised in a certain town in a certain region… They lived next door to each other and were the same age, a boy and a girl. They smiled at each other and said, “We’re going to be together forever…” Their parents also smiled at them. Some time passed, and just one day after I entered the third grade of elementary school, such a routine came to an unexpected end. “Haruka-chan….I’m moving far away from here…” “What….?” “I’m sorry…Haruka-chan…” “Hiroto-kun, I don’t want you to go…no…don’t go…” The last time Hiroto saw Haruka’s face, it wasn’t smiling, but crying… Hiroto and Haruka then grew distant. Seven years have passed, Hiroto and Haruka, who are now in their first year of high school in a faraway place, different from where they were born and raised, unknowingly meet again. They meet again without realizing it, and the cogs of their stopped clocks start to turn once more.
