Sooyoung has a good life: decent grades, great friends, and a boyfriend every girl lusts after.

So why is she so unhappy?

     It takes the arrival of Kim Jaejoong for her to figure out the answer: She's been holding back. She's been denying herself a bunch of things because staying with her loyal and gorgeous boyfriend, Siwon, is the "right" thing to do. After all, who would give up the perfect guy?

     But as Siwon starts talking more and more about their life together, planning a future she simply can't see herself in- and as she's crave for Jaejoong and, moreover, who she is with Jaejoong becomes all the more fierce- she realize she needs to make a choice... before one is made for her.
