trying to find a manhwa

i just can’t remember the name of a manhwa i read a long time ago. what i do scarcely remember was that the cover of it was a brunette lady in an orange-ish historical dress with her hair up. i semi-remember the first few chapters, in which she finds her husband canoodling with a girl he was supposed to be teaching chess(?) to. pls lmk if you know the name or what happened to the manhwa.
