The Tunnel to Summer, The Exit of Farewells

Set in a fictional city where Kasaki Station exists, there is an urban legend about an "Urashima Tunnel," a tunnel that is capable of granting one's wish—but with a price. Kaoru Touno is a high school student in a rural town in Japan who keeps to himself, going home each day on the Oosara-Sugimori train line. One rainy day, Kaoru meets a soaked Anzu Hanashiro at the train station. Kaoru tries to give her his umbrella, during which she reveals that she does not have parents, which Kaoru tells her is "good". Anzu accepts the umbrella, and they exchange phone numbers.
