Xi Luhan is the new kid, and Im Yoona is the kid in love with the new kid. In an attempt to try and find out about her new crush, Yoona has gone detective for her boy. She finds out that Luhan loves singing and always won competitions, which, much to her dismay, is something she at. Her voice just isn't made for high pitches and long notes. Her attempts to sing are more like dying cats' final wails and ambulances' screeches. But she is going to go for it, and try to sing.  She'll try for school choir with the boy she is desperate to call hers. Hey, she knows she's gonna fail big time. But maybe, she'll get Luhan to notice her and perhaps he'll help her to get every note pitch perfect...
