What is the cause of the sudden outbreak of zombie virus in Happiness, episode 1?

Yi Hyun’s latest case in Happiness, episode 1 was the murder of a hotel employee. He realized that someone in the room had covered the body with a piece of cloth. He came to the conclusion that the murderer was in the room and he was right. The mystery, however, was how the victim was murdered.

There was no murder weapon in sight, and the murderer’s confession complicated the case. He claimed to have had a drug that he got from a friend who worked in Sae Beom’s team. This drug changed him and everything that happened after felt like a dream, he said in Happiness, episode 1.

Yi Hyun spoke to Sae Beom and gave her a heads up in Happiness, episode 1. Before he could interrogate this colleague, however, she wanted to ascertain certain details and get some brownie points for playing a role in the arrest of a criminal. She had her eye on the new police rental unit that the government had planned to gift to officers whose performance evaluation was high.

What she saw when she tried to confront this criminal shocked her in Happiness, episode 1. His clouded eyes, bloody teeth from his attempt to drink the blood of another man in the team, and his repeated attempts to bite her in spite of being shot at multiple times intrigued her. She managed to stall him and isolate him but was scratched by him in the process.

The chances of being infected by the man were high, so she was taken to a nondescript research facility for some tests. She did not reflect any of the effects that her colleague had shown, but in the time that she had stayed at the facility, she learned interesting facts.

For one, she realized that there was more than one infected person in Happiness, episode 1. All of them were watching, and they seemed to expect her to turn into a zombie anytime soon. Surprisingly, though, she did not show any signs of being infected. The question now is how deep she and Yi Hyun are involved in the research and investigation into this strange drug.
