Does no one else

hmm yeah Nergal and Cliff do look alike a lot. Also, remember in that one chapter when Nergal is waking Leon up or something, and Leon wakes up saying something that got covered for the viewers, but Nergal freezes up when he hears it? I wonder what that was... there was also another part when Leon accidentally tells Nergal he thought he was someone else (Cliff maybe?) and that pisses the shit outta Neural lmao... perhaps he knows about Cliff? idk but there does seem to be a connection. all this aside, do u feel like Nergal has feelings for Leon? idk why it just seems so...

Yeah, I remember. I just picked this manga up and read it all in about two days, so it's all very fresh. He definitely called Nergal "cliff" in the blurred out bubble. I do think Nergal has feelings for Leon, that's pretty obvious, and I also think that if Cliff and Nergal aren't related by blood, they're definitely from the same world. I wonder if that's who Nergal was searching for. I remember him mentioning something about trying to find someone. I wonder if Cliff ran away from some responsibilities from his home world and had no choice but to return. . . Or if Leon was who Nergal was searching for because of his power and womb and killed Cliff and now carries a lot of guilt and also a lot of jealousy because Leon loved him so much. There are many possible scenarios right now because not many facts have been solidified yet. But there's definitely a connection between the three of them that goes deeper than I think we want to find out. Lol.

Oh I was thinking the blurred bubble was some high tier magical shit that triggered Nergal, or something that made Nergal figure out that Leon aint from this dimension?If it was Cliffs name, there wouldn't be a reason to blur it though... but maybe it was. It's hard to tell at this point. I forgot Nergal said he was searching for someone??? that's sus... hmmm if he's searching for someone and is presently still gone, then I think the first scenario u suggested seems more fitting, cuz they already have Leon, also cuz I think they mentioned that Nergal is from Dark Fall and Cliff isn't, so they aren't from the same world... I wonder what their connection is. But itd be super cool if Nergal actually did kill Cliff and Leon finds out and kills his ass lmaoヾ(☆▽☆). Yeah ur right, theres sooooo much more to this we can't tell cuz the story so far has been 90% smut and 10% lore (I aint complainin tho lolol), but Im wondering if perhaps in the end if they all turn their backs on each other lol. and you're right, its obvious Nergal has a thing for Leon, but damn like u shouldn't let the person u like get raped like, is getting a baby all that matters to Nergal like wtfffffff lmao im all in for the bumpy ride tho... this shits interesting af .(๑•ㅂ•)و✧

Well, Cliff's name hadn't been used yet and Leon's memory seems a little fuzzy so I think it was a suspence tactic by the writer. Or they just hadn't made up their mind about Cliff's name in general.
Even with the smut, the story is actually really interesting. I wasn't expecting what I got in plot. Lol. The summary did not really give a good overview.
Now that you've said it, I'm wondering if Nergal is Cliff's alertness reality/parallel universe doppelganger. And the reason that Leon is so special is because he doesn't have any. He is the only one of himself in any of the universes and that's why he's so special...it makes me wonder if killing your counterpart from the other worlds boosts your powers significantly, like Jet Li in The One.
Oh, also, I dont think Nergal actually knows that anyone is screwing Leon outside of that first incident in the dungeon. Because Mephisto clearly lied to Beryl and Deus when he said that Nergal told them to have their way with him. I mean, he literally just said no one is to touch him again. Yet. I think Mephisto is really wanting Leon to get pregnant so he can study him more. He's definitely obsessed with his research...

oh ok, my timeline about this manhwa is a bit messed up cuz of the hiatuses all year. Damn it'd make allota sense if it was Cliffes name cuz Nergal looked triggered af lol.
FOR REAl, mannn when I started it last year it was up till the point where Leon was prisoned and I WAS NOT aware that there'd be plot either, it seemed like a porno then... (well it is regardless, but still--)
WOAH THAT PARALLEL DOPPELGANGER THING SOUNDS LIKE AN INTERESTING IDEA. I haven't read The One though so idk the whole concept of it, but the way you put it seems like it could actually be what's going on rn cuz it'd be hard to explain the plot otherwise.
WTF NERGAL DOESNT KNOWWWWWWWWW?????? LMAO HES BOUND TO LOOSE HIS SHIT SOMETIME SOON THEN WHEN HE FINDS OUT LMAOOOOOOOOO istg, I like Nergal cuz he's hot af and seems pretty decent compared to the other loonies (lol someone in the comments said that u know shits messed up when Nergal seems normal as compared to the rest) but idk Leon gets Cliff flashbacks and is super upset when he's with Nergal so I don't like him..plus Leon trusted him when he was strong... but hey, even that proves your theory of them being alternate universe doppelgangers .
For real, Ive noticed the authors been making them 'have turns' (ik that sounds awful :"}) with Leon, its first Deus then Beryl then Mephisto then Nergal and then lore bomb. When he was with Mephisto last time it was SOLELY research purposes loooooool :"} even now its kinda Mephistos demons more than it is him himself... Ive read the raws (spoiler ahead: and it kinda seems like Mephisto hates Leon cuz Leons the reason his body got taken over) so yeah :"}... they're all wackos tbh. Nergals the only one who's kinda sane, I was lowkey expecting something outta Beryl but nope. Im wondering if Cliff ever had any feelings for Leon at all :"} probably not cuz he ditched him after his confession, but maybe he didnt ditch him and had other stuff to deal with so he left??? idk im more delulu bout Cliff coming back than Leon is lol. Damn I never thought something with so much rape and smut would be so interesting tho (〜￣△￣)〜
Anyways, Happy New Year love ε=ε=(ノ≧∇≦)ノ hope this years amazing for u and ur dear ones :D

oh and what do u think about that story Mephisto told Leon at the start about the last two people of the same species???? kinda seems like what happened to Leon but I wonder who that partner was (●'◡'●)ﾉ

Yeah, but like.. I thought maybe Nergal is actually Cliff when he was younger?? I'm torn apart by Cliff and Mephisto..

Like a time lapse happened? I don't think so. Their physical characteristics are significantly different. from eyes to skin color. And Nergal's blatant upset over Leon pining for someone else leads me to believe that Nergal and Cliff are either related or have a history together. But yeah, I totally like Mephisto. I've always been a suckered for the intellectual, obsessive type.

i agree with you, i think there either father and son or the same person
