Surprised, confused and slightly flattered, Nozomi responds by leaving her own letter in Setoyama’s shoebox, kicking off a secret diary exchange between the two. However, it’s not long before Nozomi learns a painful truth: these words of love were not intended for her, but for her best friend Erino.
