Orphan Serena was betrayed by Eric, her boyfriend of eight years, and her adopted sister, Monica. As the two drugged and plotted against her, five men of immense power appeared, revealing that she was the long-lost daughter of the world's top Russell family, and that they were her exclusive dark guards and fated partners. Monica stole Serena's identity emblem, impersonated her, and seized power, subsequently orchestrating schemes to defame her and colluding with gangs to ambush and kill her.
Under the protection of Victor, gang leader Roman, medical genius Sebastian, ice hockey superstar Carter, and ace lawyer Alexander, Serena exposed the imposter, settled scores with the villainous uncle who usurped family power, and showcased her top-tier abilities in finance and security. She tore up the ancient contract binding the five men, chose to accept all five men who deeply loved her, and ultimately held a sensational wedding of the century that captivated the entire city, achieving perfect happiness.
