Yeah me too. Omegaverse bought me here. So I was a little bit disapointed. But this one is a good read.
It's sentinel/guide it's a pretty new concept in manhwa I think, like omegaverse that first showed up in fanfiction based on a TV show, sentinel/guide also was TV trope that muted into a fanfiction AU and since last year it started appearing in BL manhwa
Originally Sentinel/guide was about a character with overwhelming senses like smell and sight and feral strength and the guide was this tipe of empath person who made sure that the sentinel didn't do anything bad
It seems in manhwa the sentinel became espers and the guide some kind of purifier stabilizer of their power and like omegaverse that didn't had anything sexual about it in its origins Guiding also become very sexual related
I recomend reading about it on both TV Tropes and Fanlore
it says omegaverse but I don't think it is omegaverse?? or did I miss that? I'm a bit confused
