Sitting in front of cafe. Wide shot - Rozetta sitting alone and a couple next to her. (Couple is a fantasy of her and her love interest)
cut to show close up of couple interacting/ puppy love/ laughing Cut back to Rozetta/ sing part of the song/ maybe looking at couple walking by (everyone she see is her and her crush)
Final scene - Close shot of Rozettas table. I figure walk into the scene and place the bill on the table. She looks up and its her crush. She looks over and the couple is gone/fades (make it look as if she was imagivning the perfect date.
