All Tiffany wanted for the rest of her life was a rich boyfriend to be more specific, a rich girlfriend. She has a crush on Kim Taeyeon and after some encouragement from her friends, she finally confessed to her crush. After dating Taeyeon for a week, Tiffany found out that Taeyeon was not rich and started to fall for Taeyeons friend, Yoona. However, what she did not know was that Yoona was already engaged to her best friend, Jessica and that the engaged couple really loved each other.  Friendships would be destroyed and lots of confusion would happen. It all happened because of Tiffanys undecided mind. ForewordMy crush is not rich? Why did I fall in love with her in the first place? Her friend, Im Yoona, shes cute.
