Warning rings

Exploration Stage: Festive Street
From: Detective
Description: I would like to give Juliette a ring with a special structure built into it. There is a hidden button hidden amongst the beautiful patterns that will send a signal to me if I press it when I am in danger. Will you look for it with me?
Completed: Thanks for the help. The button on the ring is inconspicuous, so if you don't even know it's there, you won't notice it first. When I press the button, a signal is instantly sent to my watch.
