Tokiwa and Asagi were just ordinary cohabitants and colleagues at a firm, until Tokiwa's birthday celebration turned their humdrum lives into something extraordinary. A few drinks later, they let their guards down and shared their deepest secrets.

"I have the ability to travel through time," Asagi revealed.
Thus began a sci-fi tale that intertwined the destinies of a time traveler and a reincarnated soul.
