To Me, the One Who Loved You
After his parents' divorce, seven-year-old Koyomi Hidaka chooses to live with his father, a researcher studying parallel worlds at the Japanese Institute of Virtual Science. Through his father's work, Koyomi meets Shiori Satou, the daughter of another divorced researcher, and the two quickly become inseparable childhood friends. As they grow older, Koyomi and Shiori develop deeper feelings and plan to marry someday-until their parents decide to wed each other. Forced into becoming step-siblings, the pair rejects this new reality. Using their parents' research, they flee to a parallel world to build a life together, but their actions soon threaten the future they fought so hard to create.
