All Hail Cousin Brother

Haunted by a terrifying nightmare of her impending doom—a life as a living blood donor for her third sister, married to the Marquis' son, Song Mingzhao, only to be drained dry over three years and ultimately killed—Yu Youyao awakens determined to alter her destiny. She seizes the opportunity presented by her visiting maternal cousin from You Kingdom, Zhou Linghuai, clinging to him with a desperate plea: "Cousin, I'll be good to you for the rest of my life." Zhou Linghuai, typically a man of ruthless demeanor, finds himself disarmed by the pleading girl with her innocent gaze. He becomes her protector, shielding her from those who wish her harm, thwarting schemes, and rejecting her many suitors. He aids her in achieving prominence and splendor. As Yu Youyao matures and events begin to mirror her dream, with Song Mingzhao appearing to propose, Zhou Linghuai confronts her, declaring possessively, "You're mine. You can’t marry anyone else!"
