My Legitimate Daughter Is in Trouble, but My Son Loves Me Too Much

When she was twelve years old, she was sold to the He Mansion and became the lowest maid in the He Mansion. Everyone called her Bitao.    She had no idea of her origins or her way back, and she was living in the midst of beatings, scoldings, and hard labor. Only her sister Yun Jin was her only light.    But there was a heavy snowfall on New Year's Eve, and Yun Jin died miserably in the snow, and Bi Tao's heart was ashen. At the time of despair, He Zhizhou, the son of He Mansion, picked her up from the wind and snow, protected her by his side, and doted on her to the core.    She is humble and cowardly, trying her best to avoid;    He got closer step by step, his affection never changed. She didn't know that she was the legitimate daughter of the Qin family who had been missing for many years. She didn't know that the young man in front of her who doted on her was her fiancé who had already made an engagement. She didn't even know that her half-sister Qin Yunyao had already regarded her as her mortal enemy and was murdering her at every step. The past is forgotten, and the identity is as dust. When the dust settled, it was time for the legitimate daughter to return.
