Lmao this is what i understand (and hypothesis) i dunno tho i havnt read the novel

So, ml had scars all over his body, but when making physical contact with mc, it disappears. It's like those 'espers' and 'guide' in other manhwas like "Profundis". So ml is definitely extraordinary, he's not a normal human. If he was, then how does he know about the past when mc doesn't even remember it? And how does he smell rotting corpse, mc didnt even realize it despite being the closest to the elder man, does he have a heightened sense of smell? Just like ml said, if the two of them stay together, then most likely nothing bad will happen to them both. And that is proven true, for instance, the disappearance of mc's frequent disturbing nightmares, and ml getting wounded when he didn't even hurt himself when mc went home to grab a few things. It seems like they are soulmates or things like that. And ml really seems to be a extraordinary-definitely-not-a-normal-human.
