Looking for a manhwa I read like AGES ago that was like Remarried Empress, but like good, because the FL befriended the "husband stealer," which was like an underage blond girl who didn't know better (bc she was being abused). The reason the husband wanted to marry/have a kid with the blonde girl is that she was a descendant of royalty with powerful magical powers yada yada. Anyway, they like kill the husband in the end or something, and the blond girl becomes the queen; meanwhile, the FL goes off to be like an entrepreneur for her boat business or something! They got their happily ever afters!
FL: Red hair(?)
"Husband Stealer": Blonde hair, underage
Husband/Dirtbag: Brown hair, brown eyes(?)
I remember the art wasn't that good tbh (don't kill me)
