Tunnel into summer, exit of farewells

---

One day, Kaoru Tono, an ordinary student, heard about an urban legend that says: if you find the mysterious Urashima tunnel and go through it to the end, then your innermost wish will be fulfilled. But legend warns that this desire is acquired at the cost of several years of life. One night, while lost in memories of his dead sister Karen, Kaoru suddenly finds himself at the entrance to this mysterious tunnel full of rumors and fears.



Suddenly, Kaoru finds that he is not alone. Standing next to him is Anzu Hanashiro, a new student who also happens to have heard about the Urashima Tunnel. She suggests that Kaoru conduct an experiment and go through the tunnel together. But questions about her motives and true purpose remain unanswered. What drives Anzu? And why did she choose Kaoru for her experiment?



Together they step into a dark tunnel full of uncertainty and danger. Each step brings them closer to the fulfillment of their desire, but also to the inevitable loss. Kaoru understands that this path can be not only a return to the past, but also the end of his future. While Anzu, hiding his true intentions, pushes them forward, Kaoru wonders: is he willing to pay a high price for fulfilling his dream?
