The mc
was a normal guy, but shitass entities took away his normal life and put him into an isekai with little hope of ever getting it back. He also completes his goal that was given to him (which took bat 10 or more yrs iirc) but despite that, he doesn’t get his life back becuz of shitty ass grading systems which are totally bias and subjective. Wouldn’t that be annoying? Maybe annoying enough to twist your character and want to speedrun it ASAP?
Also, I guess the mc kinda see’s this as a super realistic game because it has fantasy elements in it. He also basically restarted the whole game multiple times already without consequences. When the someone dies that you didn’t want to die, just kill the demon king get a bad grade again and restart! Just like a game, so would you care enough for characters in games to “treasure” their lives and treat them like real people? Maybe some people but again, the mc was a normal person, he had a normal life and etc, etc.
Also
@zabent, these are probably what you like
-harem
-super nice mc that saves everyone
-mc’s that are dumbfucks
Conclusion: he likes generic isekai that are boringly generic and are generic as fuck.
He/she is also boring shit ass human that doesn’t have any relatives/friends so he/she wouldn’t want to go back to earth but at some isekai where he/she makes a harem and everyone loves him/her.
(This is just a joke, you are probably a super athletic and handsome and outgoing guy that has an irl harem and everyone loves you.)
