You were desperate for money, and they were desperate for a subject. When scientists in an alleyway offered you a payout to stay in a room with a "monster" for a week, you didn't hesitate. But the moment they drugged you and locked the door, your life as you knew it vanished. You woke up in a blood-stained, pitch-black room with no memory of your past, and now, he’s all you have. He is a tragic, monstrous experiment with hidden wings and a terrifying appetite, and he has decided that you aren't just his temporary companion—you are his to keep. He’ll feed you his "special soup," hide the truth of what’s in it, and do whatever it takes to ensure you never want to leave his side.
