Help find manhwa

Two actually
One was a regression story were mc went back in time after dying, she was a prostitute and ml pays her to act terrible as his lover so his wife asks for a divorce in the previous lifetime mc was naive and fell for the dude and the wife humiliated her and killed her now she plans on parting ways after she is done with the wife. Mc is red haired

The second one is more vague all i can remember is that ml was either married or about to marry someone else than mc and she also gets humiliated she gets pregnant and decides that enough is enough and runs away i think she runs multiple times one she even fakes her death something about dying in the sea due to the tide
Mc is blond

In both stories the ml is insufferable and don't deserve the girls at all
Yeah I just want to recall the titles to see how they ended i think I read them both at least two years ago
