Okay, I just played through the convenience store path, playing as manly as possible, not taking any pills, and avoiding the gang entirely, along with avoiding the art thief and every other relationship.
And...the TF doesn't happen!
You still go to the fair and everything and some people see you when you fall and mess up, but no one shows up at your door the next day other than Justine, who tries to make you feel better about some people spreading a horrible rumor about you being a guy. And, that's it, the game kinda continues with work for a day or so and then hits the end cutoff.
