Synopsis：On the day of her wedding, Princess Lilith is reborn at the moment she once marched to her doom. In her previous life, while she lay gravely injured and unconscious, she secretly recorded her husband, the seemingly noble Prince Patrick, brazenly cheating with his mistress Kalixi beside her hospital bed. Betrayed and despairing, she died with the truth in her hands. Now given a second chance, Lilith pretends to accept the marriage, but in the shadows she forges an alliance with Jervis, a dangerous double agent whose covert mission is to engineer royal scandals. What begins as a cold partnership of mutual use slowly turns into genuine trust and deep emotion. With royal resources and a charity foundation as her weapons, Lilith builds her own power, exposes hidden corruption, and drags Patrick into the light of justice. She divorces him in front of the kingdom, rises as the undisputed Queen of the Underground, and, through revenge and redemption, finds a new love and a new life at Jervis’s side.
