After five years, Taeyeon decided to go back to Korea with her 4 year old daughter, Kim Seohyun. Taeyeon decided to live at U.S after her darkest day of her life but also the start of her wonderful life with her daughter. As she came home she was shocked by her father’s news that she will have her bodyguard who will live with her and her daughter 24/7. Little did she know that her bodyguard is her future fiancée.

Tiffany Hwang, she will be Taeyeon’s bodyguard/future wife. After she told her father that she is a gay her father surprisingly accepted her without second thoughts and decided to arrange marriage to her best friend’s daughter. Tiffany of course objects with her father’s crazy idea but after hours of convincing by her father she finally gave up but in one condition, she will disguise first as Taeyeon’s bodyguard to know her first before the announcement of their marriage without Taeyeon knowing that she is her fiancée, but her father didn’t tell her that her future fiancée already have daughter.

Will Tiffany accept Taeyeon’s dark past? Will she accept Taeyeon’s daughter? Will they fall in love with each other in the end or will they separate ways and fight for their own freedom?
