Effeminate dance instructors who smirk a lot and laugh at failure dance moves are not exactly Krystal Jung’s ideal type. However, this particular dance instructor – Lee Taemin – seems to be marking a place in her heart which was not supposed to be in existence in the first place. The ice princess’ facade is melting quickly, especially with those sunny smiles of his. After a year goes by, they become very close - Krystal is forced to admit that he makes her heart flutter and her knees weak. However, their relationship takes a rather abrupt turn just days before Christmas, making Krystal worry. Can she stop where things are going before it's too late? And will she succumb to the urge to make him her own?
