Terminally ill, half-human, half-beast, the owner has murder intentions for a four-year-old child. Mainly about a sick man walking through the living room to the master bedroom on the other side, silently watching Cheng _ who was sleeping. Four-year-olds should be naive and naughty, but Cheng _ is always too obedient, too clever and too precocious. He often makes Cheng Hai feel anxious and sad because he can't see through the growth trajectory, and often makes him feel great murder.
