Bang Jin Ah is a trainee under YG Entertainment who is blindly and hopelessly in love with F.T. Island's Lee Hong Ki, who, only treats her like a play thing and she knows it. But, she can't bring herself to admitt it. Her perfect Hongstar wouldn't do that right?..Wrong. 

On the evening of her of debut, right before Hongki's flight to Japan, Jin Ah fully witnesses what he is capable of and it breaks her heart. From that moment on she vows to change herself. Change to be the ultimate ideal girl, the one that every man fantasizes about, the one that will make Hong Ki weak at his knees the moment he sets eyes on her. She wants to, She needs to, She has to, BUT...She doesn't know how to.

Kwon Jiyong a.k.a G Dragon, witnessed all of Hong Ki's games and Jin Ah's pain. So when she comes to him for advice on how to get revenge, he decides to help. Declaring himself her personal Love Guru, Jiyong teaches her the ways of Love and Attraction through 10 steps that he created. It's the least he could do seeing that HE was the one who introduced her the Hong Ki in the first place.

The plan was easy: Teach her the ways of the Heartbreaker and take her with Big Bang to Japan in 2 weeks to attend the Anual Mnet Japan After Party. There, she will make Hong Ki feel jealous and regret ever taking her for granted.

But with all the time that they're spending together, will Jiyong eventually fall for Jin Ah's sweet, bright, innocent charm?

And with her feelings for Hong Ki still as strong as ever....

Will the Heartbreak finally get his heart broken?
