Overnight, she lost the chance to become a immortal with Kyuubi and he fell into reincarnation.
No one knows what happened
She doesn't know whether he loves her or not
If you love her, why do you always tell others that what he loves is right or wrong for her?
If you don't love her, why would you fall into reincarnation for her?
Thousands of years later, he is no longer the same person he was then.
But she is still her. Standing by the lake, I seem to see him saying Amo. The jacaranda flowers by the lake are all blooming.
