Han Young Won (Han Ji Hye) and Gong Woo Jin (Song Jong Ho) play each other's first loves. Likewise, the two actors are as cute as a button during their picnic date, but as drama watchers know, overwhelming happiness at the beginning of a drama is never a good sign, leaving fans wondering what lies ahead for the couple.

A rep commented, "The couple who are awaiting their marriage, become embroiled in a turning-point incident that unfolds in the production, fueling the tension... Please anticipate the random incidents that happen to the picture-perfect couple."

This drama centers around Jung Sae Ro (Yoon Kye Sang), who lost his whole family to a murderer. Although he initially dreamed of studying foreign affairs, with his family's death, he becomes involved in the dealing of jewels. A love story will unfold between him and jewelry designer Han Young Won (Han Ji Hye), who previously lost her fiance.

'Full Sun' will premiere following 'Prime Minister and I' on February 10!
