He could have agreed to do a sex tape with that actress. Not to mention he seemed fine running through the school naked and being caught. Then there was the time Bailey and Zoe watched him hook up with Elizabeth. Which he is fine with depending on your choices. So it doesn't seem like he would care all that much.
He won't show his face in the sex tape, and running through school naked after midnight isn't the same as having sex right when most people are arriving and parking their cars. The hookup with Elizabeth in the beginning is changing in the remake, specifically because it was out of character for the MC.
I still think there is a difference between all that and suddenly 10 strange women all staring at him, watching him get blown in a car, and then rushing him demanding to be fucked.
The something bad is going to happen could be that someone takes a video of him fucking 10 strange women in a parking garage, and damaging WVM's and the MC's reputation. There is a reason why women aren't allowed to talk to the MC in the hallways, we just don't know yet.
