After three years of marriage, Wen Zhiyi managed the entire household, with a monthly living allowance of only five hundred. Her mother-in-law, Ma Xiulan, dissatisfied with her persistence in being DINK (Double Income, No Kids), brought a young woman into the home under the guise of a nanny, carefully setting a trap to scheme against her son, He Jingchuan. After stumbling upon the turmoil, He Jingchuan completely shook off his filial piety blindness, firmly guarding his wife. Following clues, the couple deeply dug into a secret buried for decades that gradually surfaced. The husband's family continuously resorted to framing and fake pregnancies to corner them step by step. Wen Zhiyi picked up her long-shelved perfumery profession, embarking on a path of entrepreneurship, as the couple joined hands to meet the approaching crises head-on.
