Ji Sang did not want to directly accuse it, because it could be the actions of vampires from outside who entered the hospital. They fear more casualties if things like this are left unchecked. Ri Ta gave Hyun Woo the idea to develop a way to detect vampire body compounds that use blood serum. In any case, the vampire who uses this blood serum has its peculiarities. The bulb in Hyun Woo's mind was like the prettiest with the idea.

Jae Wook met Chairman Yoo who was waiting for him earlier. When met Chairman Yoo asked to be injected with the vaccine even though it has not been fully developed. Jae Wook refuses because it will have a bigger impact. Chairman Yoo is angry. He was upset that the vaccine could not yet be administered even though the research was funded by his money. Jae Wook brought his face closer to Chairman Yoo and asked him to calm down.
