As someone who has worked construction, it's basically a requirement to put your hair in a ponytail if it's longer than your shoulders. Pull your hair back, Rina! It's regulation! (And science!)
The teacher was an idiot in his methodology. Ren was an idiot because she's a horny, infatuated, hormonal teen.
Everyone else was an idiot because they inferred that she was being abused when she was actually experimenting with her sexuality while being an idiot in love with an emotionally unavailable, middle-aged man.
I'm an idiot because I take this shit too seriously, but still. Ain't no rape here but statrape.
I thought this would escalate, and it did, but not in the linear escalation I was expecting. More like the '45 degree angle' type of escalation, iykwim...
Whoever didn't tag this as NTR is about to get they asshole ate.
Memes aside, whatever NTR-loving jerk that didn't tag this as NTR to shock value the rest of us like this can forever stub their pinky toes on every sharp corner for the rest of eternity.
