Enter the tunnel, make a wish—but every goodbye has a price.
When Kaoru stumbles upon the legendary Urashima Tunnel—a passage said to grant any wish at the cost of years of one’s life—he’s drawn into a strange partnership with Anzu, a new transfer student with a bold attitude and secrets of her own. Together, they explore the tunnel’s dreamy, time-bending depths in hopes of rewriting the past, only to confront painful truths about loss, longing, and what it truly means to move forward. Moody, atmospheric, and beautifully bittersweet, this story blends quiet sci-fi with heartfelt coming-of-age emotion.
