An unidentified Slime Syndrome has begun to emerge in South Korea.
About
July 8, 2020. A disease called Slime Syndrome began to spread across South Korea. The cause remains unknown, though doctors suggest it stems from depression and lethargy; the exact trigger is still a mystery. Slime Response Centers have been established to care for and research those affected. Jeong Dongho, the older brother of former Slime Center counselor Jeong Hyeongjun, eventually succumbs to the syndrome and turns into a slime. Hyeongjun's sole mission is now to discover why his brother became a slime.

Intro
I came home to find that my brother had turned into a slime. The clothes he had been wearing lay atop a bluish slime, which sparkled as it reflected the sunlight streaming through the window. Without even thinking to react, I just pulled out my camera andโclick. I took a photo.
I wondered if he would return to normal if I brought him things he liked... but I don't even know what he likes.
I took so many pictures of him, yet I don't know a thing. Haha...
Even though my brother became a slime, the world kept moving as if nothing had happened. Only he was missing from my side.
He was a Slime Center counselor, yet he went and turned into a slime himself. What a joke...
Three days after he turned, my brother was reported to the Slime Response Center and taken away.
About a week passed. Suddenly, I became curious. I knew nothing about him. Nothing at all. What he liked, what he thought about, why he became a slime. Had he ever talked about himself? No, had I ever even thought about him?
Driven by curiosity, I went to the Slime Center to visit him. He was sitting still inside a cage. There were many other slimes trapped in cages nearby, but his area was uniquely quiet and still.
..Heh. Hyung, you're the opposite of me again. I'm still human, and you're a slime.
As soon as I finished speaking, Dongho's slime suddenly moved, shattered the cage, and leaped into my arms. Emergency bells began to wail and loud voices shouted things, but without a moment's hesitation, I stuffed him into my bag and ran. I ignored the sound of footsteps chasing after me.
Perhaps because of my young, athletic body, I was much faster. Arriving home, I caught my breath and naturally placed the slime version of Dongho on the sofa before sitting beside him and turning on the TV. The news was showing my face, reporting on what had just happened at the Slime Center. Ah, I guess I'm a fugitive now.
I turned my head toward my brother's room. I saw something on the desk and went to check. It was labeled 'Slime Protection Center Counseling Records.' It was likely a log of the people he counseled and the details of their sessions. I instinctively opened the notebook and began to read.
