This story looks like isekai, but its not. It’s reincarnation and time regression. There’s no need for an isekai tag. That being said, the few chapters that have been released so far are great! Looking forward to the next release.
it is said that she was from another world before. We even see her baby, thinking she would have a great life being rich. The first chapter is basically a synopsis of her first life reincarnated in this world. She died run by a horse then reincarnated again at seven.
