I'm reading the story and every word, the MC will not be a complete loser, he'll use the daughter of the old men to abuse her to work with him (or maybe for Blackmail), but for that, he'll need to be closer to her and to be better in bed (He apologised in his first time for cumming fast), that's why his mother will train him, to help the family, but the MC told his mother I'll not talk about my plan until I get some results.
The game is getting a bad reputation just because people like you, coming to a game with NTR title to complain about the MC beginning a loser.
But that's why we have 3 routes to get different levels of NTR, and looks like many players aren't able to handle the first route of Hardcore NTR so they started complaining without giving a chance to other routes.
