need help finding a manga

omg pls help, im trying to find a manga but for the life of me can’t remember the name it’s very similar to “my happy marriage”, the FL gets married to a ML from a prestigious family, and at one point she gets kidnapped by this one spiritual clan that normally stays hidden, and the chief there is a womanizer and a creep and wants to marry her, one of his wives helps her run away and that’s the last thing i remember, the FL had light, long hair and the ML had dark hair- I’ve already gone through all the my happy marriage recs on MAL and it’s none of them so idk how else to keep searching
