Blood

Ji-sang is a doctor who fights for justice and sets out to protect the sanctity of human life -- despite being a vampire.

After learning the grave secret running through his veins, Ji-sang joins Taemin Cancer Hospital in an attempt to unravel the mysteries of VBT-01.

Ji-sang wows his coworkers with his surgical skills. The new director, Jae-wook, seems pleased with Ji-sang’s reaction to seeing a patient’s blood.

Ji-sang’s inhibitors are secretly switched. Jae-wook establishes the New Drug Development Headquarters and gathers patients for Ward 21A.

Ri-ta examines Ji-sang when he collapses after being injected with a drug by some mysterious men. Hyun-woo analyzes the contents of the injection.

Hyun-woo discovers that the injection is the same drug that killed Ji-sang’s mother. Ji-sang recovers and challenges the mysterious men to a fight.

Ji-sang learns the injection made the virus stronger. Ri-ta tells Chairman Yoo about the unusual atmosphere she felt at Ward 21A’s opening ceremony.

Ji-sang loses control when his inhibitors wear off. Ri-ta witnesses Ji-sang’s wound instantly heal. Ji-tae grows suspicious of Ward 21A.

Ji-sang and Ri-ta attend a seminar on Jeju Island. After hearing one of Ri-ta’s childhood memories, Ji-sang realizes she is the girl he once saved.

Ji-sang worries that Ri-ta is avoiding him. When Ji-sang’s thirst for blood increases, Jae-wook recommends he ingest special blood.
