To Every You I've Loved Before and To Me, The One Who Loved You: two novels, two films, one multiverse.In Hidaka Koyomi's world, travel between slightly different alternate universes is commonplace. After his parents' recent divorce, Koyomi lives with his father, and falls in love with a girl named Shiori Sato when they meet at his father's workplace. But their young love seems doomed when their parents get remarried--to each other. Is there some parallel world out there where Koyomi and Shiori can be together as lovers, not step-siblings...and what could be the price if they try to find out?

To Every You I've Loved Before and To Me, The One Who Loved You are parallel universe novels by the same author and released on the same day. They can be read in either order to complement each other, and inspired a pair of anime films (also released on the same day).
