Kim Junmyeon. 25 years old. A successful man of the Kim Corporation.

Son Wendy. 17 years old. A senior of Seoul High School. 

Junmyeon was supposed to marry Son Hana but she eloped with her lover on their wedding day. 

Wendy had no other choice but to replace her sister to cover up the shame brought to both families.It was all because of an agreement made by her father, an agreement for her future.

It was a secret Junmyeon hated the most but it was Wendy's dream.

"You are a ing traitor, Junmyeon!"

"You are just like your sister. A !"

"Giving a loving glance, and sharing a warm meal together and all those other shining moments filled with love and laughter...will become your reward for loving someone unconditionally like that."
