Hyun Woo seemed to have found something. He smiled at the monitor.
Chairman Yoo exited In Ho's room in a staggering state. In Ho who was in the mesam-mesem room.
Hyun Woo explained to Ji Sang that the composition of the vaccine is quite complex, because it consists not only of a virus, but also a suppressor called hasopathoxin. This material comes from a poisonous plant that grows in South America. The unique molecular structure of hasopathoxin will react with some strange compounds. What Hyun Woo will use is sonane (the group name of Carbon number 9 methane series hydrocarbons).
This formula can spread quickly and will react in a vampire's throat by forming mucus. For humans there would be no reaction except a little sleepy. It can be used as a spray parfm. Thus, a vampire disguised as a human with Jae Wook's blood serum will be instantly visible. To make it, Hyun Woo took five days. Ji Sang refused. He ordered Hyun Woo to make it in just two days.
Jae Wook contacted Chairman Yoo to discuss a slight change in the policy of the new drug development team. For that, he asked to meet, but Chairman Yoo claimed to be on his way to Busan for urgent business for several days. Chairman Yoo told Jae Wook to speak directly to the phone, but Jae Wook did not want to.
Ji Sang runs into Ri Ta and sees her holding hands. He forced open Ri Ta's sleeves and found a blood test kit. Soon, he invited Ri Ta to talk.
In Ho tells that the VTH-16 is much stronger than he expected – after watching the data clip Jae Wook gave. Furthermore, this virus can damage the original virus (VBT-01). In other words, the person who has been infected will return neutral. The talk of Ji Tae who intends to neutralize VBT-01 comes to Jae Wook's mind. In Ho hopes they can get the source of this virus, which could be not only useful as “bom”, but also useful as a solution breaker sought.
Ri Ta was still pouting and told Ji Sang to be quiet. It just makes Ji Sang more curious and reverses the statement of Ri Ta who used to feel frustrated when Ji Sang hid his identity. In the end, Ri Ta was willing to tell her what made her speechless was her pessimistic feelings towards the genetic diseases of her family and the people around her who were hiding something from her for their own sake.
Ri Ta was intending to leave, having already told her everything. Ji Sang held her back to affirm her relationship with Ri Ta. “Then, I just didn't have a clear reason to be human, but now I have a clear reason,” said Ji Sang, “With human heart and warmth, you know, I wish I could love someone I could love forever, share my joys and sorrows. I want to live and close my eyes quietly. That's why I want to be human.”
Ji Sang revealed his intention to become a small window in Ri Ta's heart, so that the room would no longer be dark. Those sweet words made Ri Ta smile at once moved. “I will also like you, even if you are not human.” After that, Ji Sang kissed Ri Ta's lips (ah, finally.).
