Osananajimi Yome no Yarinaoshi Renai Route

Yuji Fujino and Yume Hoshimiya grew up next door to each other as childhood friends. But by high school, they had drifted apart and no longer spoke.

That distance remained between them until, one day, Yume appeared before him and said,

“I’m your wife from ten years in the future.”

According to her, ten years from now, Yuji would be killed by a new transfer student named Shizuka Tachibana. Yume had returned from the future to save him from that fate, and to marry him. The Yume from ten years in the future does everything she can to win his heart and close the distance between them, only to end up switching places with her sixteen-year-old self…

This is a a reincarnation rom-com where she’ll start over as many times as it takes to save him from a future where he dies.
