There are some rules for all the boys to know if they want to date with Kara girls. First, you can only hang out with them at Saturday night. Second, must back to home at least 11 PM. Third, you must pick up and bring the girls from and to home by yourself. Fourth, must be patient when the girls getting ready. And last, you must ask a permission by yourself from the Kara leader, Park Gyuri the Goddess.
