He courted her, he kissed her, and finally he's dating her. She, Choi Na Na, is in a relationship with the world's richest billionaire, Kim Jong In. Aware of him labelled as the 'ladykiller', Na Na continues her relationship with him nonetheless. Knowing she would eventually become one of his useless pets, she stays by his side and awaits impassively for the day to come. Why? One reason: She's hungry for love. 

Though she was dumped mutiple times and used to the routine, it was difficult to forget the continuous fears of rejection. Certainly, Jong In loves her and sets his soul only for Na Na, as he had decided to change entirely and be committed to her-- but one question; Will Na Na envisage the same? Does she trust his burning desire to turn a new leaf? Maybe. Or not, in Erratic Love.
