That's weird as fuck, but it does count as NTR.There's technically NTR but it's not much part of the mechanics like it is with their other NTR-focused games. The blond has a lover but he's only shown in the prologue and you kinda never hear from him again. The pink head has a love interest in the Kirito-looking dude and there's even vanilla scenes with him but he's just kinda there and don't really care how many guys she bangs. You can backstab him pretty hard though.
And to my knowlege (Read, translated main page through google) the dude who appears in the prolouge had a falling out with the Main Heroine (?)
Anyhow thanks for response i'll be requesting tag addition to the thread.
