Obsessive/possessive/clingy or yandere guys in dramas/movies

My kind of obsessive, doesn't want to give her up and does everything in his power to keep her by his side. Can't live without her.  Very jealous, ready to do drastic things to make sure the other guy is not in the way. LOO 10

The ML is a  yandere, but on the soft side, as in he'd never harm the FL. We are talking stalking and obsessive behaviour, he can even kill/ harm somebody(including innocent people) or himself for the girl. He does let her live her life and doesn't force her into anything, but just wouldn't stop following her around! He cannot live without her, literally, she is his everything. There is one thing he kept trying to do for her that puts his LOO to 11 in my opinion, but since I've established 10 as the maximum before I'm going to leave it at 10 ;-)

Follows her like a puppy, doesn't leave when she tells him too. Obsessive and jealous, but in a cute way. LOO 7.5

Obsessive type(hence the title haha), can't live without her. LOO 10

Obsessed with her for a long time, definitely a sort of yandere, cunning, quite evil and would do anything to keep her by his side. Appears to be very jealous, but they only show a proper jealous moment once. He does substitute for it with his obsessive and controlling behaviour though.  LOO 9

Second male lead is an evil, obsessessive and possessive yandere. I'd call him a classic yandere too, he appears all sweet until his grip on the FL is threatened. His role in this  drama is quite big and his focus on the girl is scary, heartbreaking and fascinating at the same time. He cannot and doesn't want to live without her. LOO 10

Can't give her up, possessive, crazily obsessed, a definite yandere, I'd even say too much for my taste I'd call him either evil or mentally unstable and abusive. LOO 10

Not the main hero. A yandere again, but not my type of obsessive. Very jealous, abusive and evil. LOO 10

Abusive, evil, controlling, doesn't let her go, massively obsessed, yandere.  LOO 10, but I don't really like him though

He behaves absolutely appalling towards her for the first half of the drama, so have to wait for for him to fall in love. However, when he does he turns obsessive, doesn't let her go, tells her she has to stay by his side until death.  Jealous, evil, mentally unstable and shows some shades of a yandere. LOO 8.5

Cutesy obsessive, extremely jealous, does everything in his power to make sure she remains in his sight, funny LOO 7.5

Obsessive, jealous and cunning. Not a 100% good guy, shades of a yandere. LOO 8

I must say I hated both of the MLs , but I do think the drama belongs on this list. The obsessive guy is crazy about the girl and jealous, but he keeps saying that it isn't serious, mainly because of his family. There is one thing that happens that makes him a total yandere in my eyes and I have to give him LOO10

Comes up with million ways of keeping her by his side, very jealous and obsessive, but in a funny way. LOO 7.5

The second ML is obsessive and stalkerific. He does let the FL go at some point, but has a huge difficulty dealing with it. LOO around 9, but pushing 10 at some point. 

Possessive and obsessive, but in parts in somewhat a funny way. LOO 8

There are two, the main lead and the main antagonist. The lead guy is very jealous, obsessive, forceful. He does allow her to leave at some point though. The antagonist is kind of a yandere. LOO 8.5

Massively obsessive, forceful and jealous. Tries everything in his power to get her to be with him, even if it's against her will. LOO 9

Quite jealous and very much into her, follows her around.  LOO 7.5

Very jealous and very obsessive in a funny way, but denies it being permanent. LOO 7.5

Obsessive and jealous in a romantic comedy type. Tries to come up with ways to keep her by his side. LOO 7.5

A Very jealous type, shows signs of obsessiveness, on a funny side, refuses to give up. LOO 7.5

I was contemplating for a while whether to put this drama up here. The hero in this fits the bill, but something about it felt a little unnatural. We can see glimpses of it in the first 10 episodes, then barely anything up until the last few episodes of the drama. In those he is obsessive, possessive, 100% yanderific, wouldn't let her go, would kill others to keep her. LOO 10. 

Also there is the second lead who is a stalker, he disguises his obsession by saying he wants to protect her, so I will give him LOO 6\7.

Possessive, obsessive and above all stalkerific, if his character wasn't done in a comedic way he'd appear as a total creep. This guy never gives up, follows the FL everywhere, he just doesn't take no for an answer until the very end! LOO 7.5( would have been higher if it wasn't done in a funny way)

The ML is obsessive, he also frequently gets jealous. There is stalkerific behaviour too, especially in the beginning. He is willing to give up absolutely everything in his life for the girl and I mean everything work, freedom, friends, relatives, his dreams. He is a little on the quiet and kind  side, plus he doesn't push the FL openly, so it might be difficult to see his obsessiveness at times, but it's definitely there. I was going to give him LOO 8, but there was a bit of noble idiocy at one point, so knocking it down to 7.5. 

Watched this show ages ago and wasn't sure whether I should put it on, because the ML fully lets the girl go towards the end. However after giving it some thought I think he definitely belongs on this list. For most of the drama he is uber obsessive and jealous, forces the girl to be with him, gets engaged to her, basically takes over her life. He is definitely an antihero. LOO around 9 for most of the drama, but knocking it down to 8 for letting her go.

Just a warning despite being made in 2012 this drama feels like it was made in the early 2000s. The second ML is the obsessive one. He gets interested in the FL when he already has a girlfriend, so it involves cheating. He is obsessive, forceful to an extent, manipulative, does some stalking, blackmailing and keeping tabs on her when he gets unsure or jealous of her actions. At first I was doubting his feelings for the FL, because at times it might appear like he is doing stuff to spite his enemy, but as we get closer and closer to the end (especially past 13/14 ep mark) we are beginning to see that it really is the FL that he so desparately wants. Depending on how one interpretes the ending his LOO is either a 8.5 or 10. 

One of the MLs is on the obsessive side, he has the FL followed for much of the time, wants to lock her up in a golden cage, says he won't let her leave, loses control (sometimes in a dark way) if anybody  tries to hurt her, would give up absolutely everything for her. He isn't shown to be explicitly jealous, it is kind of left to imagination and despite everything he is quite gentle and sweet with her so I'll give him LOO 8

ML is very jealous, but it is always shown in a hilarious way LOO 5. Second ML turns somewhat obsessive and darkish towards the end, he keeps chasing the FL despite knowing she loves another and doesn't mind playing dirty as long as he gets the girl, LOO 6.

The 2nd ML is jealous and on the obsessive side, he keeps insisting the FL has to be with him, eventhough she loves somebody else, has some pretty dark ideas about how he can keep her, LOO 7.5

Clingy ML, keeps chasing the FL no matter what, LOO 5. Obsessive 2nd ML, but is also sort of all over the place, so difficult to rate him. ..

Super obsessive ML, but denies his own feelings. He would hurt anybody and risk anything to keep the FL by his side. He does allow the FL to make her decision about their relationship and there is no jealous scenes at all, which knocks his LOO down to 9.

Jealous and somewhat clingy ML, all of this is shown in a funny way, LOO 4

The ML is a jerk at the beginning, but later turns really clingy and a bit obsessive, keeps chasing the FL like crazy, LOO 7

Jealous and clingy ML keeps chasing the FL in a comedic way, LOO 5

One of the clingiest MLs ever! He is like an overly affectionate puppy towards the FL, sticking to her like a glue.  This has a ton of very funny jealousy scenes too. LOO 6

Another super clingy ML who keeps relentlessly chasing the FL, has some cute jealousy too, LOO 6

2nd ML chases the FL like there is no tomorrow and refuses to give up, LOO 5. Be warned though most viewers experiece a REALLY REALLY bad 2nd lead syndrome while watching this. 

2nd ML is really taken by the FL, keeps chasing her despite her being married to another, he also turns cunning and somewhat dark trying to get her to be with him, LOO 5.5

The ML gets clingy and jealous once he falls for the FL. He has a very calm personality, which makes his jealousy sometimes difficult to spot, so I'll give him LOO 6. 

I advice reading the webtoon to understand what exactly is going on in the ML's head, which would raise his LOO to about 9, stalking, marking the FL for another guy to see, refusing to let her go and thoughts of getting rid of the competion are all there.
