I am looking for a Manhua/ Manhwa I don't truly remember but I think its a Manhua about a girl who dies in some type of ancient civilization. and gets transported into her body that looks exactly like herself in the future. But before she is put into this body the girl was going to get divorced by her husband because it was an arranged marriage. But obviously because "she lost her memory" and she seemed like a different person it was delayed. They end up falling in love but a lot of things happen. Come to find out he also was a reincarnation version of himself? I'm not truly sure. I just want to reread it.

I'm looking for a manhwa about an uncle going back in time to when his brother-in-law left his niece and move to another country right before her death in her finding out what level of power she has. This is set in a time where they have powers and battle each country. So his brother-in-law left the country and left them this huge building.
