No incest since they aren't related. Only Nio thought of Suou as family (Suou never had that intent).
Grooming is done with intent, which again, Nio had none.
Nio was definitely dense as hell. Suou was telling him he liked him in so many ways, but Nio was caught up in his own narrative that he didn't take those signs seriously.

This one was pleasantly a nie short read as long as you don't mind the incest, grooming, dub-con sex, and the dense mc. I read another one like this before where the mc raises the kid of his deceased friend and I was looking for that but oh well
