This brought Nina to a stage of emotional turmoil. It started when the last door inside him was pierced until it was filled with water. It was the point where all feelings and thoughts filled him. He felt the pain of the door being forced open, but there was also the same pleasure as when the first door was entered. The feeling of pleasure came from the friction of the walls of the door which gave a stimulus that Nina had never felt before. The pleasure also comes from his own thoughts about something going into it. Just like when he imagined an intense scene in a novel, his heart would feel it and beat as if he had experienced it. Her body responded to her thoughts and sent signals so that Nina could feel the pleasure.
