Rebirth : Husband becomes crazy after my rebirth

Not like other rebirth stories.
She lost her memories but he is willing to be with her, he lost his eyesight she will be him.
They say love is scared but at the end of the day is it really is?
People who are shouldn't be together are also the people who are meant to be together .They are happy in their own world but some aren't.
He thought she was his medicine but shouldn't medicines have expiry date.
Why do we attain a chance to rebirth?
Is it just because you can change the past all over again.
We all highly believe that no one is perfect in this novel. Each of them have their own flaws and their journey to accept flaws.
So if you want someone perfect this book not gonna place like that.
