A want to asked everyone. I looking for manhwa with female main character, who get killed by her father because she didn't have magic, but her suddenly half sister have water magic. Actually her half sister stole her magic, the father who know the reality beg for the magician to return back to the past, before he met the half sister villainess. Sorry for the bad english
I read something kind of similar. The protagonist is the daughter of a nobleman, who's daughter will supposedly save the kingdom from a prophesied drought through the blessing of the water spirits. She gets accused of being an imposter though when the nobleman's real daughter shows up and receives the blessing of the water spirits. She is publicly executed by the kingdom, and while her father doesn't participate he doesn't really do anything to stop it either. Anyway someone uses some sort of time magic and the protagonist goes back to before everything started, but keeps her memories.
