Perhaps there is more still yet to come? That seems to be the case with these ViViD games. They usually start out simple and progress to something more dangerous.

[Or that was usually the case. There was no telling with ViViD, though, especially when it was glitching. What could be a normal prom could turn into a zombie apocalypse, or worse... something requiring romance.]

At the very least, the food doesn't seem to cause any effects.
