Li Xing and Li Ming are twin sisters who look alike but have completely different personalities. Her younger sister, Liming, has been in love with Qin Shen for five years. When Qin Shen's life was hanging by a thread and he was in desperate need of a kidney, she resolutely donated one of her kidneys, thinking that the love guarded by her life would be consummated. However, she did not expect that this would be the beginning of a tragedy - her mother was deliberately hit and killed by Li's father's mistress on the way to the hospital to prevent her from having surgery. Liming, who didn't know the truth, blamed her mother's death on her own decision. Intertwined with guilt and pain, she made up the ruthless lie of "worshiping money" and broke up with Qin Shen.
Qin Shen, who was stung by five years of deep love and the kindness of donating a kidney, mistakenly thought that he was sincerely wronged. In order to retaliate, he got engaged to Xinrui, the daughter of Li's father's mistress. This engagement in name only lasted for five years, but he still could not let go of Li Ming. Many years later, Liming sneaked into Qin Shen's company under a pseudonym and tried to get close to him silently, but Xin Rui repeatedly made things difficult for him. Sister Li Xing couldn't bear her sister's suffering. Taking advantage of the twins' appearance advantages, she pretended to be Liming to fight back many times, which also made Qin Shen suspicious of this "sometimes soft and sometimes hard" Liming.
As the twin sisters join forces, the doubts surrounding their mother's death gradually surface. Fragments of the driving recorder, eyewitness testimonies, and the mistress's flaws pieced together the cruel truth. Qin Shen regretted it after learning about Liming's reasons for breaking up. The three of them worked together to uncover the conspiracy so that Xiaosan and Xinrui would get the punishment they deserved. Five years of misunderstanding, a conspiracy, and twin guardians. At the moment when the truth is revealed, all obsessions and pains are released. In the end, Li Ming walked out of the abyss of guilt, Qin Shen made up for his mistakes, and the two reunited, writing in the years that "Wei Xing leads the way, Dawn is eternal".
