A beauty queen's marriage becomes a battlefield — and she's armed with jealousy.
Season 1 • Episode 20
LatestCHIN CHONG is so pissed off that he becomes totally paralyzed, and even doctors can do nothing about it. On the other hand, CHO CHING, who has accepted the love affection revealed by KAI CHUN, urges KAI CHUN to conceal the news of his recovered vision. Ever since her return to CHIN's family, PEI PA has been getting the cold shoulder from the family. KAI SO knows that PEI PA needs to borrow money for a family emergency, so she gives her some money in private, above which she also asks PEI PA to help her take revenge against CHIN CHONG. Apart from creating more opportunities for BIK-WAN to associate more with CHING-YI, BAI-YUET also comes up with an idea to make CHING-YI admit that it was a mistake to think BIK-WAN did a theft years ago, eventually clearing her name……
Cho Tsing and her mother Cho Cho Bi Yue are itinerant beauticians wandering the country in search of Cho Tsing's missing father. In the course of their wanderings, Cho Tsing falls in love with Tsin Tung and the two become husband and wife. San Cha has been Tsin Tung's personal maid since childhood, and the two have an understanding that ignites Cho Tsing's jealousy. Cho Tsing's attempts get rid of San Cha by marrying her off backfire when Tsin Tung realises he loves her and takes her as a concubine. Cho Tsing resents having to share a husband with another woman and, when Tsin Tung divorces her, she seeks solace with another man, her former enemy Kai Chun.

Trivia, insights & behind the scenes
The title 'Lady Sour' references a Chinese idiom about jealousy, specifically women's resentment in polygamous marriages — a trope that dominated 2010s TVB costume dramas.
Myolie Wu and Ron Ng were real-life exes during filming, adding unintentional tension to their on-screen divorce scenes.
