Actor Ahn Jae-hyun and actress Ku Hye-sun admitted Friday that they have been in a relationship for at least a year.

Both Ahn‘s agency HB Entertainment and Ku’s company YG Entertainment confirmed they have been dating, after the finale of KBS 2TV’s vampire-themed medical drama series “Blood” that they starred in.

“They became closer to one another after ‘Blood’ wrapped up airing,” an HB Entertainment staff said.

“It is true that Ku and Ahn are in a relationship,” a YG Entertainment staff said.

Model-actor Ahn, 28, who gained popularity in the role of actress Jun Ji-hyun’s younger brother, acted a genius cold-blooded doctor. Ku, 31, having debuted in 2002, acted an arrogant doctor and niece of a hospital owner.
