Story is very well structured and fine tunned but there is a mishap when u see that mc doing this and that you will always start to link him with monkey in zoo. That is no matter if a monkey can solve the rubik cube it will only live in a cell.So if he start to build his plan to resist against fate(goddess) then his actions toward the goal will bring story up a notch.
Author, i thought you said this MC Was smart? First he discovers he can make a flexsble armor, That he can wear under his clothes, but doesnt make ot for himself. then he just wipes the tablet without even going through it! As a former grandpa, he should know kids usually have the latest apps. Things A.dul.ts usually dont even know existed. but he just wipes it. instead of changing the color and deleting the stuff he doesnt need.
