There are 3 different possible choices between Lara/MC after neighbour's hot-tub scene, not just the angry one. Each one leads to a different relationship dynamic. There are many similar path-points in the game. These choices occur whether its NTR/on/off.
Mixing routes is a definite no-no, in any game. That just fucks up the player experience, making choices meaningless. The bold quote is a bad idea. (The NTR-freaks would freak out) The italicised one has been suggested, but would also lead down different paths. (and it should be Lara's feelings that matter not Tony, as he is the antagonist, she is the FMC) Dev obviously couldn't handle it, so it has been ignored.
If a choice is to mean anything, then the path that follows that choice should have different content or consequences. A good dev would spend equal amounts of time on each content/path. Plenty of them manage just that, very successfully.
This dev is not one of those at this point, because only one path is being worked on to any great extent, with the others just getting a sprinkle of a few seconds here and there. Hence the disappointment by anyone not following that one path.
