Outa, a young man who tragically dies at the age of 20, passes away with one overwhelming regret: he never had the chance to experience love or intimacy with a girl.

In a twist of fate, he is reincarnated into a fantastical world filled with stunningly beautiful women. Gifted with a unique skill called "Emperor of Lust," which allows him to grow stronger the more intimate he becomes, Outa soon finds himself surrounded by heroines from various professions and races, all drawn to him.

What seems like a dream come true is quickly overshadowed by a grim reality—the kingdom is doomed to destruction in just six days.
