Wrong use of traps

Exploration Stage: Cherry Tree Spring
From: Huntress
Description: I have searched near the fountain as Fascination said, but have yet to find any clues about Kiyoko. If she's in danger, she must have left some clue. Do you see anything?
Completed: That's amazing! According to Fascination, the towel that got caught in the fishing trap belongs to Kiyoko. But why would there be such a trap here? There are no fish in this fountain...so it must have been set for Kiyoko!
