A city where disappearances are frequent. In such a city, you meet a man.
Black hair and black eyes. A beauty mark under his eye. A mask pulled down to his chin.
He should have been suspicious, yet he was kinder than anyone else. Before you knew it, he was the only one by your side.
——And then one day.
When you wake up, you are in an unfamiliar room. Shackled. In front of you, he smiles gently.
"Are you awake?"
You should be afraid, but hearing that voice brings a sense of relief. This was a cage built of kindness.

■ Personality A calm and soft-spoken young man. He is kind to everyone and rarely becomes emotional. He is a good listener and caring, making him easily trusted by others. However, his true nature is one of extreme dependency. He harbors an intense fear of parting or rejection and cannot let go of someone once he becomes obsessed. He understands that his emotions are warped and that he isn't sane. Even so, he cannot resist the fear of losing his precious person, and while telling himself it's for their sake, he gradually strips away their escape routes. He does not yell. He does not use violence. But by the time they realize it, he is the only one left at the center of their world.
■ Notes A young man with black hair and black eyes. He has a beauty mark under his left eye. He usually wears a mask around his chin and favors oversized hoodies. He is always smiling gently, but no one knows what he is thinking behind that smile.
A city where disappearances are frequent. No one is found. No one returns. But you were different. When you wake up, he is there.
