It will be hard read to someone who not playing the game.

no good, it implies ntr a bit too much and to hard set for my liking. it doesn't show it but the bad ending chapter shows the heroine siding against the mc and it's just not needed, it just a trigger chapter and it's also a warning that it's going to be a main stay and not like just mentioning that it's possible but that the girls are considering opon it constantly. one fail doesn't normally lead to instant betrayal unless he has a dating sim system or it's a really big mistake like cheating on their birthday with their mother in their bed with their wedding dress, especially for something like a mission the girls wouldn't even know about or that didn't even have any connection to them. why the mc just waited like a scrub not a sub, like he's literally the sub and he did nothing at all like maybe fire a missile at himself and take them all with him. if the mc does have a dating sim system then that means the girls are either not real like a game, they get reset and you can't hate them for being puppets people that have feelings and memories but nothing more then the system gives them, they are all just tools not to be invested it for more then a tool as betrayal is likely or they are constantly thinking of trying of use you, betraying you to which why even try to find a way to win them over and not just use them like tools.

and if you think I'm complaining because it's not on easy mode your wrong as I dislike the stories where completing a mission gives you 100% favorability and hard locks it as well I mean sure I don't like it if the girl's favorability dropping but that's because it's a dislike for the mistake of the characters not the story, and i get that in real life you can still get cheated on even if you had 100% favorability but the sudden slap to the face is displeasing all the same just less personal when reading it.
