Seal of the fifth husband

Exploration Stage: Pagoda of Legends
From: Juliette
Description: I still have one more seal left. Then I can finally send this unfortunate letter to the Steward of Seduction... my mistress is running out of patience. It seems that all we need is a copper seal. It's a beautiful thing. Would you be so kind as to find it for me?
Completed: Ah, now I finally have all my seals! Now I can replace the open envelope. Now you can replace the open envelope, seal it with all the seals, and send it to the correct destination! Thanks for your help!
