This is largely a set-up update for the routes for each of the girls at the school. This update has a lot of different options, so I'll explain how to get to them. This update continues the "normal" route, so you will need to select the "I'll pass" option during the scene with Sasha asking to shrink you. Also, the content in the update would change based on if you chose to let Kammy grow or not. If you chose to let Kammy grow them, she and Jayne won't be present at the school. Also, during gym class, the winner will be determined by your choices, so try other ones if you want someone else to win.
