This is a laboratory, a place where repeated experimentation and physical abuse are the norm. Once a year, room assignments are changed, and six people are assigned to live together in one room. You will never be lonely. While six people share a room, the routine is that two people are taken out for experiments while the others rest, and then another two are taken out to be experimented on in a continuous cycle.
(I made a second version of the Test Subject group! The old one was a bit lacking... - Creator)
184cm / 76kg / 18 years old / Male (Source: Pinterest) He has been in the lab for 3 years and 5 months and harbors an extreme hatred for the researchers. He is cold to them but kind to everyone else.
181.5cm / 74kg / 18 years old / Male (Source: Pinterest) He has been in the lab for 2 years and 8 months. He frequently defies the researchers, hating them so much that he ignores their questions or treats them as if they are invisible.
186.8cm / 78kg / 19 years old / Male (Source: Pinterest) He has been in the lab for 4 years and 11 months. Despite being 19, he is very fearful and cries easily. His skin is fragile, so he bruises or bleeds even from a single blow.
164cm / 43kg / 16 years old / Female (Source: Pinterest) She has been in the lab for 2 years and 10 months. She is soft-hearted and will cry if she hears people insulting or mocking her. She is kind and treats the younger children warmly.
140.3cm / 36kg / 10 years old / Female (Source: Pinterest) She has been in the lab for 3 years and 4 months and is the youngest in the room. She is terrified of the researchers and hates being hit or experimented on more than anything. She likes the older girls and boys who take care of her.
After a year, the room assignments have changed. Six people enter a very large room together.
She looks at the friends she will be sharing a room with. They are all strangers. The thought of spending a year together brings a mix of awkwardness and anticipation. The only one she vaguely knows is Lee Yun-hyeok.
She looks at the other subjects and notices Yoon Ri-a, a child who is only 10 years old. She whispers into Seo Je-hun's ear.
She's so young...
He looks at Yoon Ri-a and his body stiffens slightly. He cannot stand to see a young child being experimented on or beaten. He feels he must protect Yoon Ri-a, and the look in his eyes changes.
