You seem to have a difficulty understand the basic concept behind the isekai (and few other sub-genres)....
At least, the present day isekai.
Or, I suppose, you live in the past.
The character being briefly trapped in the other, often imaginary, world in order to learn a life lesson, and then returned to reality, was an isekai story concept popular within the anime (manga, light novels) roughly 20 years ago, give or take. My first experience with anime came from time where Inuyasha was still a super popular sensation, and that was a long time ago, and the stories changed since then. Evolved? If you say they devolved, I wouldn't argue with you, but if you are familiar with it, you couldn't deny they changed massively. The audience changed too. It used to be an anime for young girls back then, do you remember? If Inuyasha isn't proto werewolf romance, I don't know what it is. Now the isekai is more for male audience, and they don't want to go back to the shit they know too well.
The present-day audience wants to escape the reality, not return to it, and your dilly dallying around the protagonist's old life in the isekai story screams of "bait and switch" suggesting that you would just sent the main character back to Earth, rendering the whole story (and the isekai plot itself) essentially pointless.
Web novels are reliant on the constant upvotes, you don't want to be pointless.
