Reborn Noblewoman Swaps Marriages and Wins a Powerful Minister's Devotion

[A seemingly delicate but actually clever eldest legitimate daughter VS a seemingly cold but actually devoted and pure-hearted young lord] In her previous life, Cen Fuxiu married her childhood sweetheart, Gu Yunrong. She thought she had finally escaped the Cen household, where no one cared for her, and found someone to rely on for the rest of her life. But less than three months after she married Gu Yunrong, he brought his mistress and their two children into the house. He told her that as his principal wife, she would be responsible for taking care of the mistress and the children from then on. Heartbroken, Cen Fuxiu wanted a divorce, but for the sake of the Gu family's reputation, she was reduced to a helpless invalid at Gu Yunrong's hands. When she opens her eyes again, she is back on the day Gu Yunrong came to ask for her hand in marriage. Remembering the misery of her previous life, she turns away without hesitation. She chooses the cold, seemingly heartless young lord instead. Everyone says that Young Lord Yu spends the year away fighting wars and is terrifying, so he surely won't know how to cherish his wife. Cen Fuxiu must be out of her mind to marry him. But later, people see the young lord protect Cen Fuxiu at every turn, plucking stars from the sky and bringing her the moon, all to make her smile.
