Hyoyeon love the idea of being an adult, to do whatever the hell she want without thinking of the consequences of her actions and that's how she met him. He, on the other hand was not amused by her happy-go lucky kind of attitude and her lack of judgement. Those kind of things can get you kidnapped or killed and that's exactly how he met her. But still, the two were drawn together which may cause their mutual destruction. 

A fun love story with a twist of bitterness.
