Actually, why not try it on Selphie?

Sora considered for a moment, wondering if he should try to do more with Kairi, but then saw Tidus, Wakka and Selphie playing a little further down the beach, and his heart pounded. Why limit himself just to Kairi? Whoa, where did that thought come from?

Sora glanced at the Note, unaware of a minor effect it held. It has a way of removing the sexual inhibitions of those who owned it, though it dod not corrupt them. Just left their natural desires unrestrained.

Sora shook off the momentary confusion, grinning as he took the pen and watched his three friends playing around, before he began to write.
