Homebody Song Qingya transmigrates to an alternate era and meets the scheming Prince Tang Xinan. Since she's here, she might as well make the best of it, so she starts tinkering with little inventions, turning the back courtyard upside down day after day. Little does she know that the prince married her to expose her father's conspiracy. But as time passes, they fall for each other. "Your Highness, the Princess Consort went into a restaurant with Mu Yunxuan." "What? How long have they been in there?" "Half an hour." Tang Xinan puts down his book and storms toward the restaurant.
Little does she know that her father, Song Qingya's, dealings conceal an even bigger conspiracy.
The heroine is injured time and again, and her memories become jumbled. What could have caused it all?
Then a rival arrives: the princess of a neighboring kingdom, sent to marry into the royal family. She interferes with their relationship, and in the end, they fail to withstand the many trials. Song Qingya looks at Tang Xinan in disappointment and takes her own life in front of him. "You wronged me in this life. In the next, I never want to see you again." "No! I was wrong. Please, don't leave me!" Unable to accept it, Tang Xinan searches desperately for Song Qingya, and by a twist of fate, transmigrates to the modern era, beginning a long journey to win back his wife.
