(1970s military marriage + both inexperienced in love + sweet romance + heroine gets even the same day)
In 2025, Jiang Suining is staying up late to run experiments and finish her thesis when she suddenly transmigrates to 1975 as a delicate girl sent to marry in someone else's place.
The original owner's scheming younger sister finds the thought of a hard life following the troops unbearable. After getting together with the son of a Revolutionary Committee director, she makes the original owner take her place in the marriage.
The original owner never dares to talk back to her parents or sister, and only knows how to indulge her own delicate nature.
After the heroine transmigrates into her, she completely changes her ways. She wears a qipao, and the people in the military compound whisper and point behind her back: “Good heavens, what on earth is she wearing? She has no shame!”
The heroine turns around with a smile. “Looks nice, doesn't it? Want to wear one too?”
