The drama revolves around five characters played by the members of popular South Koreangirl groupKara. The members of Kara act as five girls (each with the same name as their real-life selves) who are given missions related to love. The drama is the Japanese acting debut for Kara, although they have previously made cameo appearances as a group in a couple of Korean dramas. Leader Park Gyuri and member Han Seung-yeon had child actress roles in several Korean television series prior to their singing debuts. "Urakara" has also been produced as part of Kara's popularity in Japan since their Japanese debut single "Mister" in 2010.[citation needed]
