Just a girl wishing for happiness.  

Taeyeon is left heart broken when the girl that she loves breaks up with her and tells her that it's just a bet. What will she do? How will a loser like herself get back one of the most popular girl in school? She was left hopeless, but that was until the bestfriend of the girl that had broken her heart, has agreed to help her.

Kim Taeyeon, Hwang Tiffany, and Jung Jessica work together to form DA:SS. DA:SS is a dating agency who help people find love or in most cases help them in getting their love. It doesn't matter if the request is impossible, what matters is how much they are willing to pay.
