Doro Doro Obake Ouji-sama

The Second Prince who was my fiancé got another girl pregnant. Along with much fuss, I’ll marry my childhood friend the Third Prince! But he seems to be under a curse. Mud Monster, I’ve heard of it as so, but n～ He’s more human than I expected? Not capitalizing on the serious setting at all, it’s just a story about a high tension heroine and a slightly S hero flirting while lifting the curse.
