Yeah, like, the irony is that it's not REALLY NTR for her (Or for any non-Asuna girl in SAO,really), yet is always labeled/painted that way when people does NTR of SAO beyond Asuna when the only REAL NTR of any of the other girls would be if they stole Kirito themselves behind Asuna's back XD I just don't particularly care for NTR, though, plus both Suguha is my favorite SAO character and I happen to like KiriSugu too, while I couldn't care less about Asuna nowadays, so I have been playing since Part 1 for her more than the main story.
That is why the unexpected twist REALLY was to my liking, as I had already accepted she was either gonna end up like Hebishima's pregnant sex pet that he would discard when another new girl he liked came along (Like the previous 98 ones) or, in the 'best' case, get 'picked up' by Inoda if Hebishima was removed from the game, which is why I never really expected Fujino to suddenly have her go borderline Yandere and start fucking Kirito while he was out of it/in the game, it reminded me of my favorite SAO H-doujin and opened up a new possibility of her being the one who ends up getting rid of Hebishima herself in a karmically hilarious twist
