Tensei shita Akuyaku Reijou wa H shinai to Shinu Unmei - Tekkoku Ou to Rouraku Kekkon

"The next time I am reborn, I want a life filled with love..." With that final wish, Emma took her own life, hoping to escape her suffering. However, instead of fading into nothingness, she awakens to the sound of applause, dressed in a beautiful gown in the middle of a wedding ceremony. Believing this miraculous second chance might be a reward for the hardships of her past life, her heart flutters with hope—until she realizes exactly who she has become. Emma has reincarnated as a villainess from a story, a woman destined to manipulate an enemy nation and ultimately face execution. Worse still, her new husband is Gideon, the fearsome King of the Horned Tribe, who immediately demands they consummate their marriage on their first night together. Emma is trapped by a cruel twist of fate: her body possesses a unique ability called "Temptation," which forces anyone she is intimate with into an uncontrollable state of heat. If she gives in to Gideon's advances, the power will trigger her death sentence. Now, caught between a dangerous royal marriage and a lethal curse, Emma must desperately search for a way to escape her doomed fate before it claims her once again.
