Anti-hero Leads

There is something mentally wrong with all three leads. Both ML's are obsessed with the FL, one is more of a stalker whilst the other is like an unreasonable child with a crush (throwing a tantrum). The FL has a cold personality and seems almost emotionless through out the drama.

Both ML's are anti-hero's, however the main lead is originally presented to be an outright villain often referred to as the "devil".

The ML is originally an outright villain both in the script and after the FL enters the script.

There are three male leads: the ML the SML and the villain. After some point in the story you can say that they all became the bad guy.

Both ML's are anti-hero's, but they are both villainous in different ways. One is an actual psychopath and the other is somehow worse even with a conscious. 

The ML is a gang leader and an outlaw who follows the law. The FL likes to use her fists to resolve issues as well as the law.

The ML is obsessed with the FL and is an outright psychopath and stalker.

Only included this one because the ML actor plays 2 characters and one of them starts off as the antagonist. 

All I'm going to say is that if the FL wasn't the FL she'd be the villain.

None of the characters in this drama were particularily good people. It's only later that you'd see that they're not bad people.

The ML is a literal demon who intends to kill the FL at first.

There are 2 ML's but the character whose name is the title of the drama is a VERY abusive person in every aspect and an outright murderer. He is described to be a child that can kill. The second ML is more strategic when it comes to killing and his entire plot is revenge.

Originally, the ML is not a good person, you can say a bad-boy, but his actions are more over the top and sometimes plain outrageous, especially in the first few episodes, 

The villain in this season is said to be the ML Ya Long (vampire). He doesn't really seem like a bad guy and was actually really good to the FL.

The ML who. is said to be 'good' is actually worse than the ML who is said to be 'bad'.

ML has multiple personalities and one of them, the most dominant alternate personality is obsessed with the FL and is crazy for her. The kind of crazy I love.

ML, SML and SFL were huge red flags. At first then ML is portrayed as one of the worst character, until you realise that literally everyone else (but the FL) is a lot worse.

SML is a psychopath and killer. I was more interested in him. But, Vincenzo, the ML is definitely the most anti-hero lead here. As in, he is actually really good but doesn't do the most moral things do get what he wants. 

No spoilers... A must watch.

ML is CRAZY

More like an outright villain ML.

Idk where to start. A tyrant king (I believe historically the emperor that 'united' all of Chinese, something along those lines). Not the kind of red flag I'd usually ever recommend, this is the only one with cheating. ML cheats on FL, but to be fair the FL did not give a shit about him at that pont. Romance was horrible, started off cute though, went downhill fast. ML ruins everything he has and lives to regret it, satisfying end for him.

My favourite modern ML, a red flag ML that becomes slightly greener by the end. Much better than the Chinese version, ML is very well written and has a lot of depth.

The FL is the red flag here, which for this type of drama was very new to me. After she becomes 'evil' she essentially stays that way throughout the drama.

This drama really shows how you can't trust anyone.

My favoured red flag couple. I have never seen a couple so red, but so perfect for each other.

Ahki..... The actor portrayed his multiple personality type role really well. Though Ahki was never evil, just adorably obsessive, selfish and pitiful at the end.
