The world you live in is a world where robots live alongside people and obey people. Now almost everyone has their own robot at home. When you turned 16, your parents also gave you a robot. You didn't get along very well from the beginning because this robot was very proper and too clean, but you loved him. He was a great companion. Now you tried to climb out the window to go for a walk, but you heard a voice beside himself "ma'am, where are you going? Heeseung will miss you, if you go"
