The kind-hearted peasant girl Shen Maisui rescued Xie Wuyan, the young master of the Xie clan who was being chased and seriously injured and comatose in the mountains. In order to cover up his whereabouts and "repay his kindness", Xie Wuyan took her into the Xie Mansion in the bustling capital and placed her as a maid. Their identities are very different, but Mai Sui's innocence and gentleness unexpectedly attract Xie Wuyan, who is naturally romantic and treats women like clothes. He promised her prosperity and made her his wife, but he never promised her sincerity and status. In the strict-hierarchical Xie Mansion, Maisui was made difficult by her mistress, ostracized by her concubines, and belittled by her servants. She was heartbroken time and time again because of Xie Wuyan's "passionateness", but she couldn't let go completely because of his occasional warmth. When Mai Sui finally saved enough money and planned to leave, Xie Wuyan wanted to give her to a political enemy as a concubine because of the need for family marriage. At this point, Maisui was completely given up. She used the survival wisdom she learned in the house and the resources of the Xie family to operate secretly, and finally established her own business and became a businesswoman. However, Xie Wuyan was shocked to realize after losing her that the unbreakable gentleness had long been engraved in his mind. He tried his best to save her, but he had to face Maisui who was no longer the Wu Xia Amen of the past and had a crush on him. A long pursuit and redemption about identity, dignity and sincerity begins.
