To be fair in the novel theres no dream like that, the smut is happening when all the trouble already got taken care of. So yeah, Im not really sure why they change the manhwa
the smut happened in the novel extras but the extras were supposedly set during this time they're an explanation of the dungeon
Uhm... No. Theres no scene of weird dream like that in the novel (I already read the novel until the end). The scene in the manhwa is yes, its in the extra on the novel, but it's when they already done with all trouble. So the manhwa changed the plot a little with showing 'the future' they will have
dude the smut in ch 59 jumpscared me so badly. i started reading this in public before that chapter since there hadn't been anything risque happening throughout most of this & thought we'd have to wait until the very end for any kind of "action"
