As he is reborn once more, he is driven by the relentless desire to avenge the betrayal that haunts him. However, in this seventh life, something unexpected disrupts his plans, causing events to unfold differently from how he remembers. "Now that we're married, whether you live or die, you are mine." By a twist of fate, Hui-kyeom becomes the favored concubine of King Jin Hyeok-wi, who shows an unsettling obsession with him. "If you try to escape, I'll cut off your legs and keep you in the palace." Caught between the possessive love of a king and his unyielding thirst for vengeance, Hui-kyeom's quest for revenge in his seventh life takes an unforeseen turn.
