Yin Qinrou, the daughter of the Yin family who grew up in love, has been Bai Yueguang in Lu Xingguang's heart for many years. When she was 26 years old, she had a night of quarrel with 22-year-old Lu Xingguang in a bar. She didn't recognize him and left with only money.
The Yin and Lu families were family friends. Yin Qinrou was engaged to Lu Xingyun, the eldest son of the Lu family, but she only regarded him as her elder brother. His parents died in a car accident due to collusion between the Lu family's grandson and Lin Wei, a female employee of the Yin family. Lu Xingyun took the opportunity to take over the Yin family. When Yin Qinrou returned to China to seize power at the age of 26, she was already trapped in a situation set by Lu Xingyun, and the company's ownership was in jeopardy.
Lu Xingguang, who had been sent abroad, returned to China at the age of 22 under the false identity of "Shen Zhou" and became Yin Qinrou's assistant under the pseudonym, guarding her silently. He caught a glimpse of her vulnerability while getting along with her, and during a secret investigation he discovered that she was adopted. He also learned about the Lu family's conspiracy and was determined to help her regain everything.
Yin Qinrou gradually fell in love with "Shen Zhou", but fell into a misunderstanding after learning his true identity. The gap between Lu Xingyun and Lin Wei continued to deepen, causing her to mistakenly believe that Lu Xingguang was her enemy. She fought among her brothers to bring down the Lu family, but when Lu Xingguang was seriously injured and on the verge of death while trying to save her, she resolved the misunderstanding on his deathbed.
While Lu Xingguang was in coma for a month, Yin Qinrou transformed into an independent heroine, taking care of him while fighting against the Lu family. This love, wrapped in conspiracy and misunderstanding, finally came to an ending that was cruel at first and then sweet after going through hardships.
