The title suggests that the MC is forced into Netori against his will. The actual game started with an interesting premise that seems to get dropped in favor of him going full villain.
The "friend" might deserve it but the girls don't. Chiaki was a true friend, MC is at fault for his problems with AI, Ema didn't really do anything except merely being rude and the whole thing with Tokuko only makes sense if she was already being effected by mind manipulation. Plus the MC figured out that his father was likely behind it but chose to go along with his plan anyway. lame.
More i think about it, the more I think the entire "help Naoki build a harem" thing was a setup by the MC's father from the start. From AI onward the plans for each girl corrupts the MC more than the last. Then there is evidence of each girl being effected by mind manipulation during the prologue.
Chiaki: Mostly believable that she would be attracted to the childhood friend with a prettier face. How easily she accepted Naoki's harem plan is a stretch though.
AI: Shows zero onscreen interest in Naoki until she is officially in the harem. While she did say that there is a guy she liked, his name was not mentioned in the conversation. Meanwhile, MC never talked to her before the attempt at breaking her so we can't know for sure that she would have ignored him like everyone else. She responded to MCs verbal assault with anger rather than the expected sadness. Suggests that:
1. the father gave false info or...
2. she reacted differently because of WHO was saying all that to her. (maybe the guy she liked?)
Very suspicious either way. MC sacrifices himself by intentionally making AI hate him which both starts his corruption and making the inevitable betrayal hit harder. Then AI becomes Naoki's blindly loyal lapdog overnight.
Ema: Not much to say here. The plan for her is downright twisted and thus probably greatly corrupts MC. She then becomes Naoki's blindly loyal lapdog overnight.
Tokuko: She has a very strong reaction to the mention of loyalty. As MC said, the compliments should not have had nearly so strong an effect if Tokuko was as indifferent about him a she acted. Just like AI, she plays the pronoun game instead of just saying Naoki. (I'm thinking she might know and dislike MCs father) She appears to be getting headaches during the last part of the conversation before heading off to the bathroom. (almost like some mind manipulation programing was trying to suppress her feelings perhaps?) It seems to me that she would have at least told him that she was leaving instead of leaving him waiting there. (you know, if she was in her right mind) She then becomes Naoki's blindly loyal lapdog overnight.
Naoki: The way he keeps downplaying the MC's contributions is at least a yellow flag. The way he and his harem were apparently talking to and about Tokuko in private strongly seems to suggest that he was already pursuing her. (with naïve Chiaki not grasping the implications of those discussions) If so, then Naoki's story about Tokuko confessing to him can't be trusted. All in all, I've got a strong feeling that there will eventually be a big plot twist that he...
a. is in cahoots with MC's father
b. is being controlled by the father via brain manipulation along with the girls
c. IS the father somehow
I know from experience with a couple games that I am capable of enjoying a story in which the MC starts out corrupting the girls but through character development gains options to heal and form genuine bonds with them. If that will be the case here and I can get confirmation then i would be willing to slog through the temporary villain route. But it seems far more likely that MC will continue down his current path no matter what.
