Gu Nan was told by his adoptive parents that he had severe allergies since he was a child, and he only ate white vegetables all year round. The first time she went to her boyfriend Zhou Yang's house, she mistakenly ate a dish containing Sichuan peppercorns but found no abnormality. Only then did she expose the lie - her adoptive parents deliberately made up the allergy story in order to let her younger brother monopolize resources. Later, Gu Nan unexpectedly discovered that she was adopted, and her biological mother was actually Zhou Yang's adoptive mother. Faced with the oppression of her adoptive parents who demanded high betrothal gifts through marriage, she decisively broke off the relationship and recognized her biological mother. In the end, Gu Nan married Zhou Yang, with the full support of his biological mother; but the adoptive parents, who favored sons over daughters and treated their adopted daughters harshly, ended up with their son breaking up, owing debts, and becoming infamous.
