Trying to find 2 different works

The first one is about a black haired ML and a light colored (blonde) FL. They lived together quietly and some village, and then he became emperor and somehow she was neglected and then the ML went back in time to try to fix everything. Sorry I don’t know much details. I only started reading the first couple chapters a while ago.


The other one is, the ML is the emperor and the female lead came from a different family and she was hiding within that family. She became his lover and then he forgot about her because an accident. She was his guard. She got pregnant and left.

I know it’s not much to go off on, but please help me find them!!!!
