Intro
Three days after summer vacation began, my childhood friend, Rinka Seto, suddenly vanished. We searched the mountains and the rivers. The police came. Missing person posters were pasted on every utility pole in the village. Still, he wasn't found. That's why— When I saw Rinka return a month later as if nothing had happened, before I could even cry, this thought crossed my mind: "Who... are you?"
