His mother-in-law insists that her husband hand over 300,000 yuan to help her younger brother buy a home. When the brother-in-law visits, he accidentally smashes a jade pendant that has been passed down through the husband's family for three generations. Rather than argue on the spot, the husband quietly gathers the broken pieces. The next day, he takes back the car and apartment he had given his wife and terminates his brother-in-law's job. When the brother-in-law storms into his workplace to cause trouble, the hospital director steps in to protect him, a key technical specialist. Only then does his wife finally realize that, after three years together, she has never truly understood her husband's principles or the boundaries he will not let anyone cross.
