Im Yoona has always considered herself a happy-go-lucky type of girl. Her pride would enter the room before she did. Who would have foretold, that the tragic loss of her father would forge for her new friendships with a group of girls who became akin to sisters to her. Seohyun, Tiffany, Jessica, Yuri, Sooyoung, Taeyeon, Sunny and Hyoyeon became her closest confidants, and role models in her determination to be the kind of daughter who'd make her father proud.

Ok Taecyeon however, is the type of boy who appeared to be arrogant, because he was. But only because that was how everyone perceived him, and who was he to try to prove them wrong? He is a member of boy band 2PM, and is a supposed big-time 'player', however, those close to him knew that Taecyeon was probably about the shyest thing around women in reality.

Kim Heechul, now this is a guy who was the culmination of the word crazy and impulsive. He could change moods quicker than the wind could change direction. He works at a CD shop across from Im Yoona's house, and when he's not being an all-around know it all and prankster, he dreams of becoming the next biggest singer/artist.

For a girl finding her way in this world, how is one to choose between the two?
