I hope the go home route fully turns into NTR i would love it as it kinda already doing. And i dont wanna hear no bitching about NTR
I'm a NTR enjoyer myself, and I can tell you now there won't be any hard netorare in this game at all. And I'm not saying that because I'm against it, but because that's fundamentally against everything Hana as a character is.
We of course follow the game through Husband's eyes but the real main lead here is Hana and she's way too strong willed of a woman to easily fall into a corruption trap like a random NPC. Literally every time she cucks husband it's to get him at the edge of his figurative seat and she does it because she's a loving wife willing to do these things for him.
At best I can see husband having a dream sequence fantasy where he dreams about Hana leaving him and getting gangbanged by a bunch of dudes, but then he'll probably wake up with her next to him giggling about saying her name his sleep or something.
