Gu Shao's Golden Canary
Young Master Gu dreams of a red-eyed ancient maid. It's only when he discovers a birthmark on his young lover's wrist that he realizes he has wronged her for two lifetimes and must now cherish her with his very life! The female lead's soul travels from ancient times to her modern self, only to discover she was a concubine's maid in her past life and is still a contract lover in this one. Resigned, she stays in her place, even helping a supporting character win the male lead's affection. Initially, the male lead treats the female lead like a canary in a cage. However, as he interacts with her more deeply, he gradually develops feelings for her. When the supporting character realizes she cannot sway the male lead's heart, she doesn't harm the female lead but instead begins to set up the male lead and female lead. Ultimately, the two find their happy ending.
