Shortly after, Mr. Gao has another stroke, and in a moment of anger, after a fight with both Simon and Wei-Wei, Wai-Tung admits the truth to his mother. She is shocked and insists that he not tell his father. However, the perceptive Mr. Gao has seen more than he is letting on; he secretly tells Simon that he knows about their relationships and, appreciating the considerable sacrifices he made for his biological son, takes Simon as his son as well. Simon accepts the "Hongbao" from Wai-Tung's father, a symbolic admission of their relationship. Mr. Gao seeks and receives Simon's promise not to tell his secret for (as he points out) without the sham marriage, he'd never have a grandchild.
