Don't know if this message will send because of the mangadex changes, but this work definitely sounds like typical barrel full of harem slop bs. I'm honestly more surprised from the light spoiler that there is no mention of how the world flips from this power balance. That said, it didn't sound like the women get to benefit from their level boost outside of the dungeon, but men by and large sound like they would be glorified cattle in this universe no matter how rich they are because if they're just exp batteries, I'd imagine there would be black markets of men being sold to rich women as portable ecstasy dispensers or illegal level boosting. Even Mr. Magnum "NTR" Dong sounds like he has almost no authority in this land, but the fact that the women faint from doping on EXP means that r*pe gangs not only exist, but are absolutely taking advantage of the fact that the women can't do anything after making contact with men.
Hopefully people get what they're looking for here because I'm not going to sit around for the next update to maybe see if they go anywhere with the world building aside from "desperate single women are hunting for high value man."
P.S.: That girl who ran off after getting an EXP hit only to become an idol so that it would be "easier" for MC to come find her seems to not understand that becoming rich and famous makes it more difficult to approach a woman, not less, but I can't expect any women in a harem slop work to have anything past one brain cell or else it would make the men look bad.
