There's a few problems with that:
- If you hit Tybalt with the tennis balls then that can be explained away as an accident. As Jill says MC is either very good at tennis or very bad at tennis, either option can explain the balls hitting Tybalt.
- If you punched Tybalt it was only because he struck first, and he obviously hasn't told his parents about it otherwise MC would have had the meeting that Chad had early on in the story (MC was at that Chad meeting so knows that Tybalt hasn't told his parents).
- If it you sabotaged the presentation then Tybalt can't prove it was your dick and if he accuses you then you can just ask him how he would know it was your dick.
And then most importantly:
- You can do plenty of playthroughs where you don't fuck Jade or Sage, you don't hit Tybalt with tennis balls, you don't punch Tybalt and you don't sabotage his presentation.
A CHICK run while going for a pure throuple, Jill or Bella playthrough would feature none of the events that make MC look like the antagonist with Tybalt, there is absolutely no reason for "Fuck, fuck, fuck, fuck" in that case.
