Shinyuu Ouji To Koshiginchaku

I was cursed to become a woman in place of the prince, and then he proposed to me?! My best friend from childhood, the high-spec Prince Vincent, and me, his follower Renoa. Though I've always been a loyal yes-man… Even if you're taking responsibility for me, I can't accept that proposal! The infatuating love story between a troublesome prince and his scapegoat attendant!
