I'm not sure if it is really 'cheating.' Then again, I didn't overly pay attention to intro interactions.
So I don't know if she and the guy are in an actual relationship or if the guy likes her or vice versa.
The only thing is the phone call cut-ins when she is getting violated and an option dialogue when it happens, I guess reflecting some type of relationship status between her and the guy when she responds while being, said, violated.
Also, I don't think rape counts as cheating really, so the whole 'cheating,' is kind of a slippery slope for tag.
