A harmonica melody pulls you toward someone you've already lost, and the show knows exactly what that contradiction costs. The romance here isn't about confession or kissing, it's about recognizing someone across time and choosing to meet them anyway, even when the ending is already written. This is a show for people who understand that some connections exist outside of normal time, and that makes the quiet moments hurt more than any dramatic reveal could.

Makoto transfers to the school in his hometown and settles into a normal, happy routine with his sister Hinata, the jokey classmate Tsutomu, Tsutomu's childhood friend Kasumi, and others. One day after school, a harmonica melody that feels strangely old to him draws him up to the rooftop. There, in the dusk, he meets Minamo, who turns to him with a smile. She is his childhood friend, though the two have lived apart for years. As Makoto and his friends go through their school days, each of them keeps their true feelings hidden, and their stories in a mysterious town are only beginning. A short-format drama and romance with supernatural elements.
