Daddy Doesn't Want Me (Not a Father-Son Story)

On their wedding night, he fell into the prince's arms. The evil mysterious man not only blindfolded him and played games, but also said that he wanted to hurt him to death just by looking at him. Overnight, he became so weird that he became stupid. He couldn't remember his enemies, lovers, or spy missions. He had to crawl to walk and had to wipe his poop. The god-like prince became a full-time nanny. He just laid eyes on him and fell in love at first sight. He actually asked him to call him "Dad"? (This is not a father-son story or a harem story, this is an emotional conspiracy, 200% sadistic, anyone looking for tears will come in)
