Accidentally Dad

Successful doctor Tung Son accidentally meets his one-night-stand from 7 years ago via a silly car accident. She claims that he is the biological father of her 7-year-old daughter, when in fact she's just trying to get money out of him to gamble. Though Tung forms a special bond with the little girl, the DNA test confirms that the child is not his and also diagnoses her with last-stage cancer.
