Okay guysss

Black. Almost as black as it gets lol. Except there will be no physical torture/abuse. But the non-con and mental torture will persist all the way to the end.

Referred it as red bcoz a black can't suddenly turn into Orange or have sympathy suddenly.
Black literally refers to causing as well as mental torture and physical torture just to make the bottom be with him or follow his words.(No day, time second for the bottom to be in peace)
Black flag is literally for example Illay for PASSION.
HE ABUSED the bottom to the point of trying to break his legs, burned down a whole forest to keep him to himself, trying to murder his friend or brother? keeping him under his watch 24/7.
A BLACK flag seme is somone whose evn willing to kill the bottom so no one can have him. His death crazy for the bottom and. His character development takes a lott of time to process.

So in conclusion this guy right here is a Red not a black.
Because The seme has not yet inflicted any kinds of deathly wound or broken his bone or any body bone yet.
His also not obsessing over the bottom like locking him up or anything or keeping him captive while the bottom is crying out to let him go or his mental health has rotten.

A red doesn't have that level of obsession like a black flag has.
For example jeakyung from jinx.
Both this guy and jeakyung has a similar personality and also has some sympathy for the their bottom with times but they act tough and haven't realised their feelings yet.

You clearly haven't read the novel, so I will let your wrong opinion slide.
If the manhwa follows the novel, which up until this point it did fairly faithfully, you'll change your tune soon enough.

I don't know, how you feel about spoilers so I won't go into too much detail but Zigryl is an obsessive, possessive, narcissistic, violent criminal psychopath, that kills people for literally no reason without a second thought other than because he can, and lets not forget, he is a rapist to boot. A pretty unrepentant one at that and he'll only get worse.

Jaekyung is just a self-absorbed asshole, who knows martial arts, probably with some tragic backstory to kinda explain (if not justify) his behavior.
Zigryl is just a psychopath, that unfortunately has the power (and lack of consequences) to act as he wishes and takes full advantage of that. He also seems to be a bit of a sadist, although given that for the most part he doesn't hurt Kay too much physically, that might just be his lack of empathy that makes him have no regard for Kay's pain (and even enjoying it. He probably just thought, he deserved it, more than truly being a sadist).

I think, one of the biggest difference between Zigrly and a lot of other red flag tops is, that THEY usually change their tune somewhere along the line. They realize their mistakes and usually grovel for forgiveness (which given the fictional setting, is usually given way too easily). Oftentimes they also have some sort of sob story or there is a misunderstanding, that at least explains their bad behavior.
Zigryl is unrepentant from start to finish. He doesn't change at all, if anything, he just gets worse because of his obsession over Kay. That, plus his penchant for murder, rape and violence, is, what makes him a black flag and not just a red flag.

Bro.... In this recent chapter he hasn't still shown his black flag character yet. He still has the red flag character which Is y I pointed it out as a red flag turning into Orange.
Not many read novels and don't what to be spoiled which is y I referred it as red flag according to how the recent chapters are going with. And he still haven't shown any black flag charcter behaviour yet.

For the novel yes I already got spoiled by others who kept on mentioning even tho not needed witout evn tagging it as spoiler. So to avoid others getting annoyed like me.
I'm hiding the fact bcoz spoiler means we know how it is, how it will end and will get bored of it.

And so you can recheck my comment again
I mentioned
"Don't have hope" bcoz I know his not red.
"We never knw what's ahead in the future" bcoz he will show his true color later.

And the reason y I gave u a comparison is bcoz I myself thought u haven't read the novel yet. Which is y I didn't agree with your point on him being flag.

He has raped him, he disregards his feelings, he HAS physically hurt him before, he constantly belittles him, makes fun of him and looks down on him. He is violent and kills and hurts people without a second thought.
Those are all things, that HAVE happened in the manhwa already, so yeah, you can argue all you want, but you are still wrong. He clearly is a black flag already, not 'just' a red flag. But lets just agree to disagree.

I know I might be judged for this comment but I second that the ML is not a black flag. I'll write down below some points for what reasons I believe it without giving spoilers:

1- Not a black flag so far. Not if we use the tag to define ML's behavior when it comes to the MC. I can't recall him reaching the level of violence of a black flag against the MC and I have read until the last chapter of the novel.

2- This ML mostly take advantage of the MC and takes pleasure of his flesh (MC's) and this is a trend in BL and very abundant in the market (as r*ape, mental &/or physical ab*se, etc.). I'm not defending any of these behaviors. It is what we have in the market.

3- The ML has not remorse or whatsoever to do and cause harm as he pleases against secondary characters. Wouldn't expect less when feeling jealous or possessive. As plenty of MLs in most of the KNs, JNs and CNs.

4- This ML does harm and has not repair in treating others like ants or bugs. Sometimes just reminded me that he's a royal and they look down on the rest.

5- He could be even worse. The author could explore and exploit more this fictional persona. Royals and tyrants could go "off with your h*ad/l*mbs" anytime. There's room for improvement in the dark side.

Anyone can argue about it. We don't have to think the same. I respect everyone opinion.

If you consider his personality as black flag....and not red than you haven't read or know worst about other.
This guys personality and character is totally different from other Black flag tops, quite not to the level of being called Black flag but can be considered but his not entirely a black flag.
And ya grapes? It's not an uncommon thing anymore in bL nowadays but that just can't be used to describe him as a black flag.
Never read omegeverse? Guide verse?
There's literally grape, and all the things you've mention which you consider black flag but in omegaverse and guide verse it's mentally hurts them bcoz either they are an omega(the lowest) or a guide(if low rank guide) but they are actually red and later turn into an Amazon forest.
On the other hand kills people(not so much but I read some that contained almost killing them or harming them ) Ofc yes the top has killed people but mostly he killed are those who are not worth to live, his enmies, the zombies. And on the other hand, his a royal and the scenario of him to be considered black is completely different. During the olden days, literally everyone makes enemy of each other. So far I've read I've never seen him kill an innocent person yet.
I've already read other black flag manhwa's which I even left em halfway.
This top right here is just a half of what actual black flags are suppose to be his not evn to the point of black nor red.
Just a dark red flag he is.
Plus if he was a black flag then why in the recent chapter did he think about the bottom sympathetically? Why did his emotions waver just bcoz the bottom said 'not today, his tired'?
A Black flag never care about their bottom and go through with their own way.
Not only in this recent chapter but their are also other chapters where the top thought about that bottom and left him alone.

Are you telling me or the other person becoz I don't completely agree with the top being a black flag considering his wavering emotions and empathy to the bottom in the recent chapters and also in the way back chapters.

I'm saying that I agree with your point of view and added those points as reasons why I do so. I didn't want to answer in the others thread and make it escalate. I loved the "Amazon forest" in your last comment btw.
