@Akunoko
There's some overlap. However, if you can read the text, he clearly asks her to "Become his woman" and she accepts. NTR is a territorial-based fetish. Dude came in from outside boyfriend's territory and changed a person within that territory forever. Even if it is a different from more extreme forms of NTR, it still counts. Girlfriend now belongs to the NTRist. She became his. That qualifies for NTR, even without a breakup.

Whether or not we get a sequel where she breaks up with the original boyfriend, I don't know.

And Harry doesn't mind if he doesn't make the scene: he's got a daytime job he's doing alright. He can play honky tonk just like anything. Saving it up for Friday night. With the Sultans...
With the Sultans of Swing!
