The uke was reincarnated in the book, since he knew everything he was hailed as a prophet. But after the book is done, he basically lose his use. His fiancee broke up with him since he can no longer predict, etc etc. Then that's when the prince/hero came in ? (don't remember if its a prince or hero, the hero is basically yandere) and (had sex) took him in his place.
I'm sure its manga with one shot BL.
