what if there's a girl working inside SME as a choreographer but she didn't believe in love.Except that Yunho who too oblivious about love have to work with her but everything seems wrong to them will they realize what actually is going on and able to retrieve each other or someone else will interfere?there's also Junsu who always make her happy and actually has a heart for her and there's Lee Joon who hates her at first but finally fall for her. at the end..who will win her heart?
