Due to a misunderstanding, Lee Soo and Kyung Woo Yeon have held a crush on each other for over 10 years.
Lee Soo works as a photographer and he is attractive. He is also mistaken for a model many times. Kyung Woo Yeon works as a calligrapher. She has had a crush on Lee Soo for the past 10 years, since she was 18 years old.
Ten years ago, Kyung Woo Yeon was as innocent and carefree as any eighteen year old might be. With dreams, ambitions, and a heart ready to love, it was only a matter of time before she fell for someone. And fall she did; for her friend, Lee Soo. Unable to hold her feelings in her heart, she confesses to him before he leaves and gets friend-zoned.
