In this Korean manhwa, a royal from another world is welcomed into a family with a secret. His stepmom, a stern teacher, struggles to maintain her composure around his youthful vigor. His step-sisters, one a timid little girl and the other a confident young woman, can't resist their growing attraction to their new brother. As they explore their newfound desires, they engage in heated, familial encounters, their bodies entwined in a dance of forbidden passion, their moans echoing through their royal halls.
