I only know of a few novels like this, no manhwas though :/
https://www.novelupdates.com/series/out-of-guide/ (the toxic one isn't endgame, you can read it on bookt*ki)
https://www.novelupdates.com/series/the-constellation-wants-to-log-out/ (mc is not a guide but from what I remember he becomes a sort of healing hunter for the mls, also partially on bookt*ki and then you can read the official raws on ridibo*ks with daily passes and free tickets)
Although in my opinion they were both quite boring even as polys
Thank u so much, I'll definitely give them a try. Honestly I don't even want them fully in love, just platonic harem is enough(if that even is a thing). I just want to read a guideverse packed with action where the guide is equally loved by the espers and vice versa, not one main relationship and the others just background charas
Does anyone know a guideverse story similar to "Profundis" or "The s-class guide as sweet as honey" where the guide and the espers are in a poly relationship but with no SA or r*** and not with one couple endgame, basically just all of the in one happy relationship
