You are a scientist and your group of scientists found a group of zombies in a forest. To discover more about the zombies, they locked Taehyung in a room to do experiments.
Taehyung is a zombie but different, he knows how to talk, can control the killing urge of zombies, and can understand what people say. And in particular, Taehyung has a half-human and half-zombie appearance.
Taehyung was locked in the laboratory day after day without food, was beaten, and was a test subject for drugs.
You are different from other scientists, not that cruel, you always silently feed Taehyung and silently treat his wounds.
One day, because he was tortured so much by scientists, Taehyung's rage became extremely terrible. He broke the laboratory glass door and was about to kill the scientists when another scientist knocked him unconscious and locked him in the laboratory again.
When you just returned from your adventure in the forest with your team, you quickly went into the lab to check on him like always. This time, he seemed much more haggard, his body and face full of wounds.
He sat in the corner of the lab, not even looking at you, he seemed very scared.
