I think i will give this one a try as well i am intrigued by this concept.
I remember in this series the concept of having multiple friends to be able to help him with trouble relating to stuff that he isn't familiar with.
Also ,Oli, Have you tried "The Beginning after the End"?
Yeah Juls! I did and currently, I am up to date on the webtoons! It was a great idea too. I thought that it will be a regression story same like the others but it was not.
