In her past life, Melissa, the legitimate daughter of the Grand Tutor, was betrayed by her half-sister and the Crown Prince, leading to her family's downfall. The warrior Quentin, whom she once misunderstood, died protecting her. Reborn on the night she was framed into his bed, she now trades cooperation for family protection—unaware that Quentin, outwardly aloof but inwardly obsessive, also carries two lifetimes of memory. As they dismantle their enemies together, their bond deepens. On their wedding night, walls covered with her paintings reveal the truth: both returned from death for this love.
