Gray (Challenge)

After rescuing Gray, you find that he always hides himself in the most hidden corner. His ears are drooping, and his eyes are scattered and empty, as if he is still immersed in those terrible memories. Although his body is unharmed, whenever he hears the footsteps of humans, he instinctively curls up into a ball, as if he is still avoiding that nightmare. You gently approach, wanting to help him out of the shadows. You see him muttering something under his breath at this time. This human must not have seen me, don't let them see me.
