What are Joy's requirements?

[Glimmer]

I read a guide that said it needed Smarts + Fun + Creativity, but that's definitely untrue.

I had all those stats over 20, as well as succeeded every event with her, sat with her at the Campfire and sided with her every time, and she still turned me down at the end.

Googling either brought me back to the guide that was wrong, or the author of the article simply said "We don't know her stat requirements", which really does not help.

I believe the other stat required is charm. The guide you can buy in-game mentions that she likes sexy people.
