"RUNA, BABY, before we go to the party, let me give me something that you should always bring with you every time we go to the royal palace."

Right now, Runa was in the room with her mother while preparing for Vera's birthday party.

"This is a voice recorder that I brought from Korea," her Mommy-ya said while showing her the cute flower brooch in her hand. "I tested it earlier and it works. This is battery-operated, though. So, you must only use this when you have to."
"But how will I know if it's time to use it, Mommy-ya?"
"Our Runa-ya is smart, so I know you'll figure it out," her mother said. "Am I right?"
