Lol, I see people saying their going to drop this every week and comments like "Why do people even read this, the art isn't even very good for ecchi. etc."
I think if you look back through the comments throughout the chapters or even the korean scanlating sites; most people have the same reaction and it kinda makes sense why so many people are keeping up with it(besides the ones that are just teenagers fapping to it):
Consistently hilarious, yeah it's crude humor, if you've gotten to this point and the horse ahegao turned you off the manga, I'm surprised you stayed this long.
Not that it needs one, but the story is half-way decent, especially for an isekai. You've got our chad MC getting typically isekaid, but he doesn't die. He's re-awakening within his old body on Earth, but each time he gets thrown out the window by a thot that looks like one of his companions in isekai land.
The isekai world is ridiculous, but the author at least made it intriguing enough for readers to actually look forward to learning about more. WTF is this giant slug monster, why are there only females in this world, is this actually an isekai or is he living in a post-apocalyptic future? Best thing about the world-building is the questions get answered, and the author drip-feeds the info so it doesn't get stale.
The author has the formula down to keep readers interested, and fappers fapping.
