Yuma and Saku discover a mysterious pendant that suddenly sends them back in time to 1990. There they meet the younger version of a gay bar owner whose life was shaped by a devastating heartbreak. After hearing his story, Yuma becomes convinced that if they can change the past, the man might avoid the tragedy that shaped his future. As the two travelers move between past and present, they confront the realities of life for gay men in different eras and question whether altering history can truly change love and destiny. The story mixes time-travel fantasy with erotic encounters typical of the pink-film genre while reflecting on missed chances, queer history, and the difficulty of rewriting the past.
