Kdramas & Cdramas With Obsessive or Psycho Second Male Leads

SPOILERS AHEAD:

At first it seems like he slowly descends into villainy but later I realised he was very manipulative even from the beginning. He seems nice but turns into a villain as the drama progresses.  Female lead was not the only reason he went to the dark side, but she was a huge part of it. 

Also, the actor who plays the SML is SO DAMN GORGEOUS AND GREAT WITH ACTING! There is a scene in it in which he shows so many different emotions in a single scene, without saying a single word.  

Absolutely loved his character'S obsession 5/5

SML is an ahjusshi, older than FML. He is a powerful man, and is willing to do anything to keep FML by his side, he is that obsessed. 

I rate his obsession 4/5

SML is a total villain, and his obsession with the female lead is pretty unhealthy and he seems unhinged at times. He had no redemption qualities. 

I rate it 3.5 out of 5 though, because of some reasons. 

SML here is also a total villain. Yet he loves the FML. I use the word 'love' instead of 'obsession',  because I really believe he did love her. He was not obsessed to the point of keeping her by his side even without her consent. But he was a villain, a heartless baddie who only had a heart for the female lead. 

SML has a very unhealthy romantic obsession with the female lead.  Sometimes its even creepy. 

This SML is not THAT obsessive. But he is a bad person and is obsessed with the FML. He has redemption qualities though.

The psycho guy who is obsessed with the FML is not a SML. But he does have a romantic interest in the FML. He has been obsessed with her for a long time. He was really handsome yet creepy. 

The villain, who is really handsome, is obsessed with the FML. He kinda cares about her too as he went easy on her many times while he was really cruel to others. Still he was a total psychopath and did hurt the FML a lot. 

the SML is also the villain and is really cruel. But his character is overall very comical. I liked it though. 

SML doesn't admit that he likes the FML but he does a lot of bad things under the guise of 'righteousness'. It's apparent he is doing it because he likes the FML. He was actually really unlikeable. 

Both MLs are jerks. The SML seems like a nice person in the beginning but he starts to become bad. He had an obsession with the FML. 

The SML is a total jerk. But he stays obsessed with the FML throughout the drama. Even after he has married someone else, he still cares for the FML. He lies about something because he doesnt want to help the FML save the her master because he is jealous.  Didn't really like him. 

There is a creepy obsessive stalker in this who can be considered the SML. He was really psycho. 

Both leads are obsessed with the FML, and the main ML can be considered the SML too for may reasons. He is totally psycho and cruel. Both MLs were selfish and cruel but did many things to be with the FML.  Cruel and manipulative. 

The SML is an obsessive villain. 

The SML is in all the seasons of Arthdal Chronicles. He is obsessed with the female lead and is a total anti-hero. Cruel, manipulative. 

The SML is a total simp for the FML. He is cruel, psycho but very much smitten for the FML. People liked his character better than the ML.

The SML is obsessive, possessive and does many things to separate the FML from the ML. He isn't totally psycho, but turns into a jerk and threatens the FML to come to him. 

SML is totally manipulative and cruel. He is obsessed with the FML  and when she refuses to be with him romantically, he goes on full psycho mode.  He does very cruel things to the FML out of jealousy and obsession.  He is 5/5 on the scale.
