SUP lruska. I recommend you read the article on this link, it helps a lot and will definitely improve and maybe make you notice mistakes you didn't know you have committed or improvement you hadnt thought of, but know that its just a guide, no a rule on how to write.
Give it a read, its not long. Im sure you will be surprised
Did you thought about having Theo filming Yui do something cute and possibly sharing it on isekai website COUGHYOUTUBECOUGH ?
This one i am less sure: just in one sentence saying -> a surge of videos about grand daughters began to appear in order to compare against Yui (done by idiot/pampering parent/grand parent). Or just to also be popular.
I finished my fucking task of going to doctor and following to a store with my father when going back and now i need to be depressed waiting 3 hours until your next chapter... =_= It became too interesting with MC becoming so OP and crushing evil.
Damn you blood tears eater ! You and your evil scheme of creating a too good/awesome story, only to give not a lot of chapters everyday, all so you can eat the readers' suffering of wanting more ! Or maybe your idea was to make us addicted to it and paywall the future chapters ! DAMN YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Damnit... i can't pay online. Would have paid (only) one month like for 20-30$ once / donation so i can binge read and be satisfied and wait a lot of days to continue read the rest free (when series in scribblehub catch back to 98).
Would have done that because got this big craving today/right now because you stopped at the really good part damnit.
Somehow reading your series, what i want is pure wish fulfillment. MC having no problems in human city because he is OP and even if enemies appear they are crushed in one chapter.
It's hard to find stories that are can be light hearted or really relaxing/healing.
(I am at chapter 67)
