He Remembers All My Lives

She has no memory of him. But he remembers it all. Every lifetime. Every encounter. Every version of her. Sometimes, they are strangers. Sometimes, they are friends. Sometimes, they fall helplessly in love. And in one lifetime, one of them dies. Until, in one layer of existence, he finally makes a vow. A hard vow he fights to honor at any cost to keep her alive. Because he comes to understand that maybe the reason she dies... is not that he failed to save her. But that he is the reason.
