We can’t assume that the game decides which relationships are consensual or not, to the game everything you do is consensual.
It can absolutely be canonically non-consensual in some playthroughs: (Warning)
if Tav tries to break up with AA once tadpoles are gone, he refuses. From that moment on and during the epilogue, where you can once again ask for freedom and he will refuse, this relationship will be abusive and non-consensual. If people want to tell me that refusing to allow you to break up with someone is not non-con, then okay, their opinion, for me it's absolutely and irrevocably non-con.
