are there any mangas that are about someone ruining some elses life like psychopath yaoi

Psycho (Young Dream)

Not really extreme yaoi tho but the plot is very interesting

i tagged these mangas as 'psychological' and 'twisted' which may or may not have a yandere character, but the overall theme and ambiance are similar
