Taeyeon was the kind of person that never fell in love, while Tiffany was the typical popular girl. They had been together for a long time, but Tiffany's new annoying, clingy, selfish attitude made their relationship into an one-sided love. But the question was, did Taeyeon really think she didn't love Tiffany the same way Tiffany had love Taeyeon?

Who would've thought, that a businesswoman turned housewife could ended up being trapped under the charms of her husband's beautiful mistress.  (Previously My Lover, His Mistress.)

Tiffany Hwang, South Korea's most popular actress fell in love at first sight with a mere restaurant owner, Kim Taeyeon.  She was sure she wanted Taeyeon more than anything, well, before she knew that the Kim Taeyeon she fell in love with, was the Kim Taeyeon that bullied her everytime she visited Korea from America. That midget, evil, bully Kim Taeyeon from her childhood years. But Tiffany was too late, she was already in love with her evil midget.  

Taeyeon was the university's goddess, popular, a playgirl and had never fell in love, well not until she met Tiffany Hwang, your typical, beautiful, normal and one of the top students in Soshi Architectural Institute. The two was pretty much typical, just like every other stories, Miss Popular had to be in love with Miss Nerd. What was uncommon was their relationship. Taeyeon had to pay every week to have Tiffany as her girlfriend. Because apparently, Tiffany,

Tiffany had never felt so human. Not before she met Kim Taeyeon, a victim turned love.

Taeyeon had accidentally hurted her girlfriend's feelings over an argument. Tiffany ran away from their shared apartment and it was Taeyeon's responsibility to look for Tiffany. So, how did Taeyeon ended up being carried at the back, by none other but her angry girlfriend?

What would happen to Taeyeon when she and her enemy Tiffany are alone in the same house? Will it change her hatred towards Tiffany, or, will she fall harder?
