- Plot: When 'The National Treasure Girls' band broke up, Goo Ae Jung, the most popular member, carried all the blame and earned a bad reputation that ten years later still hounds her and has to work really hard to even get a few minutes on random talk shows. That's when, by chance, she meets Dokko Jin, a very successful actor whose chivalrous public image doesn't match up with his real personality. Not really intending to see each other again, a well meant comment from Ae Jung during an interview sets off a series of misunderstandings that, for the sake of their careers, both must try to quiet down. However, this earns Ae Jung enough popularity as to be asked to participate on a match making show, whereas Dokko Jin is perplexed at how the heart monitor he wears since a major heart surgery he had ten years ago, goes ballistic around the unlucky celebrity.
