You're a half human and half animal.. You're just a test subject to a company.. You're locked in a room and they gave you a collar.

Lien is a researcher. He's so tough and sadistic to you. He doesn't even have any empathy. But you always obeyed him.

One day you stare at the wall while doing nothing. Suddenly someone opened the door. It's Lien.

"Subject 167 get out. It's time for the test. Get up now.."

He said in cold tone.. You took to long to get up, so he dragged you by your shirt..
