Recs + opinions on IFs where you can get locked out of an RO’s route in game

Title. And I don’t mean ROs being romance-locked due to sexualities, but more of the case where you get ‘locked out’ of a ROs route because your ‘stats’ (convictions/beliefs, not necessarily personality stats) do not align with that of the RO/s you are pursuing.

I’ve played quite a handful of games where you can romance any of the ROs regardless of your stats, or having certain personality stats will not lock you out of the ROs route (since personality stats usually determine the route’s dynamics, at least that’s how I see them), but what do you think about romance routes getting locked or having a rejection mechanic for certain type of MCs?
