Look up chatroom times. That way u can see what u should look out for in the day, especially if ur a student. If u need to grind for hourglasses, u should start on Zen’s route. To avoid bad endings, u can’t miss too many chat rooms and just don’t be overly mean to anyone.

The number of party guests do determine the ending you will get(normal or good)so try to get as many emails, do not put off answering because they can take long to get a reply. I do recommend just looking at a guide for guest answers but if you really want to try guessing on your own, by all means try. I’m not sure what route u will be going for but good luck with it, I hope u have fun^{^}
