3. Vampire Prosecutor 

Starring Yun Jung Hoon and Lee Young Ah

The only person who knows of his secret ability is Detective Hwang Soon Bum. They end up working together in a new joint department between police and prosecutors solving murder cases. They are joined by rookie prosecutor Yoo Jung In, and intern Cho Dong Man. Together, they solve murder cases, and Tae Yeon must use his "powers" to find leads on seemingly unsolvable cases.
