Yeah apparently even i was surprised by that..maybe we lost the plot a bit or could be the team who chopped off some parts of the novel (if it has one I don't remember)
I believe they actually dont have monsters nor guild in og world but its likely he just wants to be a hunter? Yk
like example some people says they want to be hero even if its unlikely they will
No, I think what happened was:
When Jehee regress, there's a different time line that was created. Instead of being transferred at age 29, the world MC got transferred when he was 9yo. This TL worldMC lived in the game until 29yo. Then Jehee defeated the key master in this TL, and 1 month later worldMC got transferred back to his world while sleeping.
What MC's mom mean was that when worldMC got switched with gameMC, the gameMC always talking about his dream (being a hunter) because he was a 9yo kid whom I assumed still got his game world and the true world confused. That's why his mom said : aside from that (the being a hunter dream) the worldMC parents is giving their 100% support for their child (who was gameMC until lately)
So in conclusion, this worldMC is back to his normal world. The one which didn't have monsters or hunters roaming around. (I was a bit confused too at first, but re-reading chapter 60 and 61 once again enlightened me)

So, was the real world mc we were following the game mc all long? And the guy thats here now the real world mc? And, weren't there no guilds or monsters in our original mc world or was there something I missed in the first chapter?
