Can make people display flowers that reflect their current feelings. When Nully just puts in casual effort, the person's flowers reflect the emotion they want to convey. It takes more effort the more the other person is trying to hide that emotion (whether from themself or others), to the point where dragging a secret out of someone might have some kind of blowback on Nully. (And also to give it a way for it to not work when OOCly we want it to not work etc.)

If approved I'll set up a quick-n-dirty guide in my journal that people can follow if so desired.
