I forgot the title but the story is about he was transported to another world probably have systems as well I think? The people trusted him because he looks handsome but he killed them instead.
So basically he's a villain. The cover as I recall he has a white coat. Its not Reverse Villain btw.

Is it perhaps this one?

Does anyone know any manhwa/ga where the main character was reborn and is the pet of the (important person of the story) without them turning into a human, just being the pet.
