That relative want her back after all this time? You had so many years to find her and now when finally she married and hit away from that awful family, you want her?
The MC was hidden away by her mother bc the mother didn't want to marry the Itohara clan Lord, nor does she want to stay in the clan. The clan lord didn't know of her existence until that time in the ball. He wants MC for selfish reasons
