So,I have been watching Cheese in the Trap, and strangely ,I quite enjoyed his stalker habits...I don't know why,makes things more dark and interesting.

If you know dramas or movies with a strong stalking element,please write it down :)

Thanks for reading^^ 

I Believe Park Shin Hye's character in Flower boy next door is a stalker with social anxiety. She keeps stalking the guy she likes but she is unable to face him directly because of her anxiety, until she gets help from the other guy played by Yoon Shi Yoon XP I Believe that is the plot in short.
Dr. Frost - there's an episode where there is a stalker. really a stalker
isn't ''last friends'' a bit about stalking. Didn't watch it but saw some scenes about a guy that kept calling etc. 

There's also quite some stalking in ''clone baby'' though it isn't in a romantic kinda way.

And Gap Dong is also quite a stalker
There is a stalking story in "you're all surrounded". It last for about two eposodes.
Thank you all! You guys recommend stuff that I had no ideia about :) 
Also,thanks for not commenting on my rather strange taste haha
Orange Marmalade (2015) the male lead stalks the female lead in the begining
There's quite a lot of stalking in Secret (korean drama). The male lead keep his eye on every movement of the female lead. No wonder he slowly starts to feel love :)
