Finding Mr. Destiny (2010)

Gi-joon starts an agency that helps people locate their long-lost first loves and Ji-woo becomes his first client. She is dragged there by her worried father, Captain SEO, who learns that she's still hung up on Kim Jung-wook, a man she fell in love with on her trip to India in her early 20s. To identify the face of Ji-woo's long-lost first love, the two travel all around the country and come face-to-face with a smörgåsbord of Kim Jong-wooks. After days on end of little success in their search, the agency receives a single fateful phone call: an inquiry from none other than Kim Jong-wook himself, hoping to find Jin-woo through Gi-joon's agency. Gi-joon tells Ji-woo the good news but, having realized his feelings for her, Gi-joon turns and runs back to Ji-woo.
