Anyway, there's something else. As soon as White Day ends, a new event starts! A personality switch.
What does this mean? Your character's personality will change completely. Let's take someone with a simple personality! Syaoran? Usually he's polite, determined, shy, dorky. During this event, he'd become rude, shameless, undecisive and probably lazy as well.
Think less "completely OOC" and more "opposite" to the usual behavior. How severe or not the effect is can be up to you, same regarding the character realizing their behaviour is odd or unusual.
It lasts from Saturday until midday on Sunday! I'm making it short since this sort of thing is hilarious at first and then it becomes really tiresome very quickly. If you've got any questions, just ask!
During the whole day, all of Kiseki will be decorated with WHITE. And white teddy bears and other cheesy mushy crap, but that's it. It'll look like a giant hospital /o/
