The day Taeyeon wanted to confess to Tiffany was the day Tiffany was going to marry Wooyoung,her childhood best friend and crush.When Yuri,Taeyeon's best friends,told her about Tiffany's marriage,she was sad but said that she would attend the wedding.However,while Taeyeon was going to the destination,she was hit by a car and was sent to the hospital immediately.Tiffany was sad that Taeyeon did not attend her wedding and hated Taeyeon straight away.

Taeyeon was broken hearted when Tiffany did not want to see her or talk to her anymore.None of her friends except Yuri believed that Taeyeon was caught in an accident.

2 years later,Taeyeon became the CEO of her father's company.She was popular amongst everyone but was still single.Wooyoung and Tiffany were the opposite.Their company was going bankrupt soon so Wooyoung planned Tiffany to work at Taeyeon's office to steal ideas.While this was happening,Tiffany started to have feelings for Taeyeon.

Will Tiffany help Wooyoung or will she follow her heart and go to Taeyeon instead?
