In the quiet seaside town of Tsukishima, there is a legend—one that no one dares to prove.
"On the night of the longest dusk, when the sun refuses to set, cross the old wooden bridge at Kageri Lake. A wish will be granted, but something must be left behind."
Sixteen-year-old Renji Asakura is desperate to turn back time. After an accident leaves his younger sister in a coma, he becomes obsessed with the town's legend. When he finally finds the bridge at sunset, it is exactly as the rumors say—suspended in a never-ending twilight.
However, he is not alone. Mikoto Shiranagi, a quiet but sharp-witted transfer student, is also there, carrying her own secrets. The two form a reluctant partnership, discovering that each time they cross the bridge, they can rewrite the past—but only by sacrificing a part of their own future.
As Renji and Mikoto continue using the bridge, their memories start fading, their bodies weaken, and time moves forward without them. Renji must face the ultimate question: How much of yourself are you willing to lose for the people you love?
But the bridge has rules, and breaking them could mean losing everything—forever.
