Killing stalking in movie

Guys, if you want to see how sangwoo’s murder in action, watch The Chaser 2008. It is a korean movie I am watching and it is hella creepy af! The killer in that movie is crazy and creepy and reminds me of sangwoo he might not be as hot though lol
Seriously recommend because it gives me the chills and makes me stop fantasizing about sangwoo. I mean, sangwoo is motherfucking hot, so it is hard not to wanna fantasize about him. But this movie makes me change my mind. I am scared of killers after all... and I think we all should take killing stalking more seriously than just an enthralling yaoi not-real story :(
