am i the only one confused? what's happening??

they are inside a memorial dungeon while trying to save the s class hs girl (forgot her name huhu). it gets a lot more convoluted here on out so it’s better to read the novel and come back here because it won’t make much sense if you wait week by week for the chapters

Read the novel.... This manhwa artist are good at illustrating the novel but the wait will make you forget the deets so better to read the novel and come here to reread
