Lovely Yandere boys (NOT BL)

An isekai story with beautiful ML! The motivation of FL to isekai is close to zero (she fell for the Villain of the story and didn't want him to die). No death, no bad environment, just pure (unrealistic) love. But still. She gets there and gets a mark (that only soulmates get) and hopes that hers is ML (and I LOVE the way it turned out). While ML's just a crazy man who had an awful childhood and has blood on his hands. And no, he doesn't fall for her at first sight. Strongly recommend!

He's a cute yandere, she's a smart woman. The plot is just unfolding. but should be interesting!

She is a Shut, destined to a life of undying love towards one person. He is a Destroy, always on edge to hide the violent outbursts they’re known for. Just as FL is coldly rejected by ML, a string of horrific murders threatens their lives and the investigation creeps ever closer.

She's a girl haunted by a ghost since her childhood. He's the ghost who haunts her and takes body of her crush's dead youngest brother. They were married ~1500 years ago and now he wants to kill her to take his revenge. But can he?
Not sure whether he's yandere in the end, but for now - he's a little psycho with the urge to kill her and protect her at the same time. And he's damn strong.
