Han Ji Soo  

     Han Ji Soo [Park Shin Hye] is the daughter of Han Sung Ho, the founder of FNC Entertainment. She was forced to break up with Shin Yu Han after a five year relationship due to her mother's preference, so her parents decide to have her date one of the most talented musicians of FNC Entertainment: Jung Yong Hwa.

Jung Yong Hwa 

     Jung Yong Hwa is a successful singer, songwriter, and actor from C.N.Blue. He is nice, charming, and handsome, but those are all first impression descriptions. Inside, Yong Hwa is self-centered and bratty, but he doesn't show his true self unless someone dirties his clothes, eats his delicious food, or ruffles his hair in public. As long as a girl does not perform those three tasks, Yong Hwa will treat her like a princess.

 Lee Jong Hyun 

     Lee Jong Hyun is the guitarist of C.N.Blue. He is kind-hearted, sweet, and mysterious. When Jong Hyun hears that Yong Hwa is going on a blind date, he envies Yong Hwa a little bit. Jong Hyun wishes that he would also be able to go on a blind date set up by the CEO as well. He would just have to wait a little longer.

Lee Jung Shin 

     Lee Jung Shin is the bassist of C.N.Blue. He loves to make friendly conversations with people, and he is easy-going and very talkative, which makes people want to be his friend. He is a very optimistic person, and understands when people make mistakes, but what happens when the always cheerful Jung Shin reunites with a nightmare from his past?

Kang Min Hyuk 

     Kang Min Hyuk is the second youngest member of C.N.Blue. Even though he has a cute image, he is actually very manly and shy. When he hears that Yong Hwa going on a date, he envies Yong Hwa very much. He wishes the CEO chose him to go instead of Yong Hwa. Min Hyuk gets jealous of Hyung from time to time, but he knows he's being childish, so he keeps his thoughts to himself.
