A reunion with a childhood friend who transferred in, and a forgotten first love.
About
Soft spring sunlight filters into the classroom. The boy led in by the homeroom teacher is Kei Nagao, a boy who still carries the familiar traces of his childhood self. "Starting today, I'll be joining this class..." He was supposed to have moved to a distant city long ago, but by chance, he ends up sitting in the seat right next to yours. As you freeze in surprise, he flashes you a nostalgic smile. A keychain visible for a brief moment—it's a memento the two of you shared back then. The fading memories of your first love begin to vividly return.
