I literally just finished watching the movie ''Kurosaki kun no Iinari ni Nante Naranai'' and I really like the bad-guy in it.
Does anyone know a similar drama/movie with a guy that's lowkey very mean but very possessive of the girl? It doesn't have to have a love triangle. 

Le Jun Kai (chinese) dude is horrible until the end...

Secret (korean) curretly waching so idk how it ends but dude is obsessed

Itazura na Kiss - Love in Tokyo (japanese) dude just doesn't know how to display his emotions
