If the anime changes the banter between the MC's to be less flirtatious or bold or irregular than normal manga garbage for fear of losing otaku fans I will fly to Japan and beat up 1000 nerds.
The dialogue literally makes this manga. You cannot change it.
I agree with the sentiments about the dialogue and interactions being the core thing about this manga/novel. If the anime changes anything I'll just drop it and hope someone translates the novels.
