Daddy! You're Spoiling the Wrong Kid

What she wanted was a quiet life with her daughter, whom she had raised by herself for six years after one night with a man she did not know. She never had his name, and he never had hers. He was a boxing champion who had been framed, and that was the night he met her. Six years on he traced her, but her older sister had taken her place and was passing herself off as the mother of his child. The sister moved into a rich household with a girl named Lin Zihan and used every opening to make things hard for the real mother and her daughter. "You wicked imposters, just wait and see how my mommy and daddy kick you and your kid out!" He did not know who she was, but he kept putting himself between her and the sister, and he fell in love with her.
