[Ancient-to-modern time travel + modern-to-ancient time travel + satisfying revenge + switching places in arranged marriages]
Shen Tingxue, in both ancient and modern times, takes her own life for love. A temporal mix-up brings the two women together in a room caught between eras.
Modern Shen Tingxue: “Your parents don’t care about you, and now you have to marry into a poor family with a vicious mother-in-law and a bunch of awful relatives, just to live a life of hardship? No problem. I’m an expert at lying flat. Who cares about rules and propriety in the modern age? Helping the family make plans is completely out of the question. A pampered rich girl like me only knows how to eat, drink, and have fun! Sister, I’ll marry in your place!”
Ancient Shen Tingxue: “Three years of love came to nothing, and my fiancé turned around and fell for someone else? And he falls for every woman he sees? Whatever. They’re just a bunch of concubines. Bring them home and take good care of them. She’s pregnant? Even better. That saves me ten months of trouble! As the young lady raised by the entire general’s household to bring honor to the family, I know how to win power for myself while bringing glory to my family! Sister, I’ll marry in your place!”
So every night, in that room where time and space run amok, the two identical Shen Tingxues compare notes and help each other devise plans.
Ancient Shen Tingxue: “That poor old woman still makes you stand around observing all those rules every day? Here, take this subway commuting gadget and some superglue! You can stand for seven or eight hours without getting tired, while she’ll be stuck to her chair. Let’s see if she gets worn out!”
Modern Shen Tingxue: “The third, fourth, fifth, and sixth mistresses are too noisy? No problem. Ancient times have all kinds of medicines. Let’s poison their voices first and enjoy some peace and quiet!”
