Mysterious Giver

Exploration Stage: Bridge
From: Martha
Description: I cannot put her soul to rest if I don't know what exactly is preventing it from going into the world of spirits. Fortunately, I've managed to sense the girl's aura and understand which items could be connected with the trouble that's keeping her at the Airship Dock. The first one is a bouquet. Not an ordinary one... but a flying one. Can you find something like this?
Completed: The bouquet tied to this balloon is enveloped in sorrow. I feel that the trouble keeping the girl's soul at the Airship Dock is connected with the person who gave her this bouquet.
