Su Wanqing, the concubine of the Shangshu Mansion, mistakenly married the Prime Minister Lu Wenyuan in her previous life. She was left out for half her life and died in depression. Only when he was about to die did he realize that he was just the substitute of Bai Yueguang in his heart - his sister Su Wanqing. When she was reborn at the age of fifteen and was about to propose marriage, she resolutely avoided Lu Wenyuan's marriage proposal and chose Shen Yinci, the loyal and brave prince who was of a lower family background but full of sincerity. After getting along with each other after marriage, she discovered that all the "coincidences" with Shen Yinci were all his affectionate plans for many years. The two of them worked hand in hand to face the ups and downs of the inner house and the outside world, and finally achieved consummation and spent their lives together.
