Im not sure if the mc is just dense or straight a fool. Not only after the regression he always said eres this eres that like he doesnt have his own brain to think(cmon he is not even a parrot), he literally trying to swallow up those sentences as a whole without even think about the borderline, but ofc since there is a plot armor he would be fine whatever he do. But me personaly it just feel frustrating and annoying to read.
