Ren Akiyama falls asleep beside Hana Mori after fourteen happy years together and wakes at twenty-one, before they have ever met. Convinced that their life was cut short and somehow returned to him, Ren sets out to find the woman he already knows as his wife and rebuild the future they were supposed to share.

At first, everything feels familiar. The same bookstore waits on the same corner. The rain comes on the same afternoon. Hana walks through the door just as Ren remembers. But memory cannot recreate timing, chemistry, or the thousand small choices that once brought two people together. To Hana, Ren is still a stranger. To Ren, she is the person he has loved for nearly half his life.

All the Lives I Loved You is an emotional anime-inspired romance about second chances, memory, and the difference between trying to repeat love and learning how to find it again.
