Three Billionaires Claim My Son

Xia Zhiqing was thrown out by her own family after she got pregnant from a night with a man she never saw again. She raised the boy, Xiaobao, by herself, and he has a rare blood disease that costs money she does not have. Old Mr. Meng notices the child on the street and sees his own family in the boy's face. A test says the Meng bloodline is there. Which of his three sons is the father, nobody can say, and all three of them say it is theirs. Xia Zhiqing is brought into the Meng household as a nutritionist so she can be near her son, and finds her stepsister Yao Mengwan already there, having spent years being treated as the woman who once saved the old man's life. That was Xia Zhiqing. Yao Mengwan works steadily to get her thrown out, and when that fails, to get her hurt. Xiaobao is injured and the three brothers all come running, which forces the question of paternity closer to an answer. Xia Zhiqing finds herself drawn to the eldest. Then a little girl walks into the house and calls the third brother her father.
