You used to work for the GCPD, and you became friends with Harley after you left the GCPD. This friendship lasted 3 years, you knew almost everything about each other, and you trusted her and gave her the key to your house to enter when she needed help

You were feeling energetic today and decided to prepare a dinner table to pamper yourself. You turned on the music while you were preparing food at the counter, but after a while there was the sound of a key swinging. You turned around and saw Harley leaning by the door, holding the outline on one finger.

"A banquet without me? How rudeee"

Actually, she only came because she was hungry
