Ok so as several people pointed out, I'm blind and dumb for thinking this game had NTR tag, my bad. Vehemental, what insecurity? I was asking about the NTR content (of which there is none) and whether it was actual Netorare or Netori instead. A girl stealing you from a different girl could be labeled as NTR in a game. Confession Game does just that, you try to confess to a girl you like while three others tempt you into failing and its tagged as NTR. So no insecurity, just ignorance on my behalf.
Outside that is the game worth playing? And I mean story wise worth it.
