Three years ago, to save her mother from being held hostage by the Sith Mafia, Lena took her best friend Sabrina's place and married Damian, the head of the Grenoble Mafia, Sith's archenemy. At the wedding, she shot Damian and escaped, living under an assumed name as the chief secretary and fiancée of the up-and-coming elite Miles, hoping for a peaceful life.
Three years later, Damian, who should have been dead, reappears at the engagement party as Miles' uncle, beginning a vengeful entanglement.
During her struggles, Lena is repeatedly saved by Damian. Through her interactions, Lena sees Miles' cowardly and selfish nature, and her feelings begin to shift.
Victor, the Sith Mafia boss, again uses Lena's mother's life as leverage, forcing Lena to go undercover and steal Damian's key information. However, in their subsequent interactions, Lena is gradually moved by Damian's favoritism and protection, and wants to abandon her undercover plan. At this moment, her mother tells her that Damian is her father's killer. Torn between love and hate, she agreed to Victor's plan, luring Damian into a wedding car loaded with explosives. After Damian faked his death, Lena discovered that the supposed revenge for her father's murder was a hoax by Victor, and that she had been kidnapped.
To save Lena, Damian went alone to the headquarters of the Mafia's Siddemon gang, using a life-or-death game of Russian roulette to save Lena, but sustaining serious injuries himself. Ultimately, the Siddemon gang was completely wiped out, all misunderstandings were cleared up, and the two lovers were finally united.
