A member of the new drug development team peeked out from the window glass. He seems to be following orders from Kyung In, who asks to be sent a research plan by a new drug development team through a secure email channel.
In the end Ji Sang comes to Jae Wook's place. Soon she demands an explanation from Jae Wook about how to consume human blood without hurting her. Jae Wook answers from the blood trade. Ji Sang gasped at the confession. He asked, is not blood trafficking illegal? Jae Wook confirmed, then invited Ji Sang to think from another perspective. There is someone who is infected with a rare disease and needs treatment. The world provides these medicines and patients just buy and take the medicine.
“Unfortunately, a rare disease that we aspire to not known to the world community,” affirms Jae Wook, “What we need is blood that does not come from within our own bodies. Therefore, we have no choice but to find another path. The way by paying. I do business with blood sellers in India. There, buying blood is legal. Of course, receiving the supply from there the price is quite decent.”
Manager Woo returned to his room. Eun Soo who again ate ramen was startled and hurriedly stood up. Manager Woo told her to keep eating. Moments later, in a surprising way, Manager Woo asks how long has Eun Soo worked with him? Eun Soo mentioned about six years.
Manager Woo later stated that he would create a very innovative research project. He said he would test Eun Soo first before starting, whether Eun Soo was worth it or not. She asks who Eun Soo believes in: her father or Jung's manager? Eun Soo declares the person she trusts is Jung's manager. Directly, Jung's manager declares Eun Soo passed (what the hell is this exam?).
Jae Wook says he has done some research and concluded that red blood cells stimulate change. In addition, red blood cells cause the smell of an infected person to become more pronounced. Ji Sang continued, “So the reason why I can't detect a strong smell from you is this?” Jae Wook justifies. Even so, the most important thing is the nutrients that will support the physical strength of infected people, namely albumin and globulins. That means blood serum.
Ji Sang felt his hypothesis had been wrong, because he thought red blood cells were the main component supporting serum change suppressors. Jae Wook did not blame Ji Sang's hypothesis, but it was only a temporary boost. He mentioned that people who are infected and consume human blood will have more power. Ji Sang asks how did Jae Wook outsmart his body temperature, heart rate, and high frequency signals?
Back in Jung's room, Eun Soo who reads the data states that what she sees is very dangerous. He couldn't say what he was seeing. Manager Jung asks Eun Soo to identify more accurately. Eun Soo draws the conclusion that the data she reads is most likely a virus or some kind of cancerous blood. He flipped to the next page and found an old photo containing an old doctor, a woman, and a small child. Eun Soo asks if Manager Jung is that kid? Manager Jung agreed.
