Dude. Just shut the fuck up. You're completely delusional and retarded.
Whether that was NTR is not up to the author to decide. Words have meanings. You don't just get to redefine shit to gaslight people about what you objectively did.
Heck, even you admit you thought she was a love interest - until she got gangraped and killed, and now you have to rationalize it because you can't face the fact that you got NTR'd. You're like a beaten wife telling people "you don't know him, it was my fault".
You're so pathetic it's not even funny. Just disgusting.
