Magic mirror?

Exploration Stage: Path of Petals
From: Haruo
Description: That you really don't know what happened to the cherry tree? Or are you just pretending not to know? Well, all right, let me help you out. Someone left a cosmetic box in the tree. Find it and look into the mirror.
Completed: What did you see when you looked into the make-up box? It is enchanted, and the mirror reflects your true image. What do you mean it's no different than an ordinary mirror? Well, it seems that the magic has already worn off.
