Gu Hye Sun sports a no-nonsense look in stills from the upcoming vampire Korean drama Blood. Unlike her usual sweet-but-spunky characters, this time Gu is taking on a colder role.

Blood tells the story of a vampire (Ahn Jae Hyun), who also happens to work as a surgeon. Gu Hye Sun plays the female lead, Yoo Ri Ta, who is an exceptionally talented hepatobiliary and pancreatic surgeon with striking good looks. She is also quite arrogant. Her character has been described in early press releases as a Paris Hilton-like doctor (which sounds more terrifying than a vampire doctor, to be honest). Ji Jin Hee also rounds out the cast.

Blood will reunite the PD/writer team Ki Min Soo and Park Jae Bum, who previously worked together on Good Doctor. The KBS series will take over the Monday/Tuesday slot starting February 16, following the conclusion of Healer

This all sounds like an exciting combination! What do you think of Gu's latest look? As we wait for this series to begin, you can catch Gu Hye Sun's last drama role in Angel Eyes:
