I literally keep a save at the only NTR scene in the game(cause it's not in the scene gallery), and you have 2 decision making moments where you get clear warnings of NTR.
This is the only moment of NTR in this, and is only forced because in the current build of the game you don't get the option to take the pills that suppress Red, so it's like a forced teaser that you can still skip, and there's no implied NTR in this, and the dialogue actually changes to show that nothing happened between Mary and Darnell in the time it takes the MC to get there.
So no, there is no unavoidable NTR in this game, implied or otherwise.
Also I'm unsure if this is how the NTR route will start for sure in later builds of the game, where you have one day where you go while taking the suppressing pills and then after this almost-NTR moment, you can decide to stop taking them. Or, it could be a choice before this event where you just decide whether to take them or not, and you can avoid this event entirely. Got no clue till the NTR update comes out.
