Damn, that's... ANNOYING AS FUCK! Not the fight or the story, it's peak, but... WHY DID I DECIDE TO CATCH UP RIGHT NOW?!?! If I'd waited even a month or so, I could have seen both this conclusion AND the aftermath...
edit: now that i think about it, I REALLY hope that this isn't the end of this story despite what the card said. It feels like a massive cheap out with the whole "undetectable" stats thing. I feel like it's only there so that people who enjoy Lookism and this story can't say one manhwa is stronger than the other. If that's the case, they shouldn't have even given us a look at Johan's stats or better yet, not include any characters from Lookism at all.
Another problem I'd have if this is where the story ends is... What the hell is the purpose of the system? If they chose the main character specifically to fight against Choyun and his goal, the question then becomes why the hell did the system choose Choyun in the first place? Shits and giggles? Even that has so much potential. Maybe there's multiple versions of the system? Choyun's system was purple, Soohyun's was blue. What exactly IS a Challenger Card?
I genuinely think this story has so much more potential than just this arc. Wasn't Choyun planning on unifying the entirety of Seoul? That in itself already has so much potential if Soohyun finds a valid reason to pursue that goal in Choyun's place, which shouldn't be too hard especially since they've already added Lookism characters into the story and made them actual characters with stats that we can see.
I can believably see the characters from Quest Supremacy surpassing, or at least matching, Lookism characters in strength after a certain period of time. It's a reality-warping system that can turn a weakling nooblet into a a martial arts master that can use UI within... what, maybe a few months? Less? Too much potential for this story to just end within a dozen or so more chapters.
