The Yandere Prince's Fiance Is So Naive

It was love at first sight for the 3rd prince of The Emerald Royal family. Benjamin Lionel Emerald-Rar'gonath is not one to fall for someone at first sight, due to his beautifully terrifying face, his dark and hollow emerald eyes, very long black as the endless abyss hair and a scar going across his left eyebrow down to bottom of his left cheek.

Though meeting his fiance ended up bursting hidden memories of a life before his own the moment she was introduced to him. Modern education and knowledge explode into his brain as well as an unhealthy obsession with his beloved fiance who look exactly like she was in her last life.

Now if only that dark voice that came along would stop talking about some reincarnation, this world being some popular game and getting rid of some future pests that going to be bothering his beloved fiance.

It really bring out the demon side of him from his dear mother out just hearing his soon to be wife fall for another prince other then him or some worm framing his plump munchkin for say prince.
