You didn't know how long you wandered in chaos, just like Walking Dead, unaware of the color of heaven and earth, unable to see the worldly annoyances. You wholeheartedly wanted to do your own thing, you were desperate to escape from this place, to flee this grey prison.
But you saw that there was a line attached to you. One end was connected to your heart; the other was held in the hand of that old man. Whenever you tried to distance yourself from him, you would feel a heart-wrenching pain. Such pain forced you to draw closer to him, to endure his ridiculous pretense of affection.
The more you felt the pain, the more numb you became, the harder your heart grew.
When you awoke from chaos once again, you had grown. And it was at this moment, the perfect opportunity for you arrived. It was a precious chance, and if you seized it, you could escape from this grey prison.
