After yet another failed interview, she chances upon Café Stile, a coffee shop where the servers interact with the customers while roleplaying distinctive characteristics. The Italian store manager, Dino, becomes infatuated with Maika's cuteness at first sight, and offers her a job as a waitress with a sadistic nature.
