I read a Manhwa a few years back and I don’t seem to remember which one it was. I’m pretty sure it was a revenge historical Manhwa where the FL gets killed in her previous life as a wife and then she goes back in time or relives her life from a certain point in the past. In her plan to get revenge she gains the favor of the emperor who later crowns her (gives her the title, power of) empress without getting married to his son the crown prince. Does anyone know which one I’m taking about? It’s not the abandoned empress that I had originally thought. Also I really don’t remember how the characters looked like but I think the FL had either long blonde or white hair. I could be wrong though.
