The In-Law Boundary

The In-Law Boundary Plot:

Su Xiao, a newly promoted advertising planner, has been married to Chen Mo for six months when her mother-in-law, Zhou Xiulan, suddenly moves in from her hometown to "take care" of the couple. However, the mother-in-law's "thoughtfulness" soon turns into overstepping—rummaging through Su Xiao's personal items without permission, selling her all-night planning drafts as scrap paper, and even secretly altering her pregnancy plan by contacting her doctor. Already stressed from work, Su Xiao finally snaps when Zhou Xiulan gives away the pearl necklace left by Su Xiao's late mother to a neighbor, sparking a huge argument. Chen Mo is caught in the middle, torn. It's only when Su Xiao stumbles upon Zhou Xiulan's old diary that she learns the truth: after losing her husband years ago, Zhou Xiulan used "control" to mask her loneliness—she feared being "cast aside" if she wasn't "useful." In the end, Su Xiao teaches Zhou Xiulan to make short videos, and Zhou Xiulan learns to "knock before entering." Through their adjustment, the two women realize: family love isn't about overstepping giving, but standing outside each other's world and knocking gently.
