Jihee is a student at Hanyang University with major Mass Communication, her uncle is a producer at Music Bank and he asked her to help them at music bank to handle the artist and she approve it. One day she has to handle MBLAQ in music bank, she has to follow them on rehearsal until the day they filming. At that time Lee Changseon (leejoon) falling in love with Jihee, because she has a cute face, and then Joon told GO that he likes her, and then GO ask Joon "how if we make a bet? if you can catch her i will give anything you want" and then Joon say yes.

Two day just pass, Joon meet Jihee again at KBS studio again and they talk a lot, they changing phone number each other. Joon thinks that he already won, but he doesn't know that Jihee's brother is GO friend, so GO ask Ohyun (Jihee's brother)  to help him. But, Jihee told her brother that she likes Lee Joon because he flirted Jihee everyday. Jihee didn't know yet that GO and Joon try to get her, and her brother always try to make Jihee and GO closer.

3 months passed, Joon ask Jihee come to a coffee shop to meet him and GO, at that coffee shop GO and Joon purpose her to be their girl friend, and of course she wants to be Joon's girl friend. Jihee and Joon was very happy until when they go home Joon ask GO "형 where is the present that i asked you? me and Jihee are couple now" and Jihee say "what??? so you guys make as a bet?" and she break up with Joon at that time.

Day by day Joon keep thinking of Jihee everyday, when he filming on music show he always remember Jihee. He regrets why he makes Jihee as a bet when he knows that he really likes Jihee very much. After that day he always try to contact Jihee but she never respond it because she still mad at Joon and she also feels so broken. Everyday Joon looks so sad, and then GO also feel so guilty to him, so he try to help Joon to get Jihee back to him.
