1. I completely forgot about that blackmail part at the beginning of the game that threw me off when I saw it. thanks for jogging my memory.
2. while I 100% agree with you on the Chika point in fact im just not even gonna pursue her anymore, It should be pointed out that A. its not NTR because there is no romantic and exclusive relationship between the MC and her. and B. from a dev POV its hard to justify tagging this game as NTR since thats the only instance of any of the love interests having relations with another man so for people who like NTR they will be sorely misguided if they download this game with the expectations of there being actual NTR content.
3. this doesn't pertain to just you but i see a lot of hostility towards the dev and their supporters and vice versa and if the direction that the dev is taking Chika turns you off the game that much I don't see how hard it is to just say "hey not a fan of the direction of the game i don't plan on playing it going forward" and then just deleting the game, there are plenty of games out there that are exactly what you're looking for
