The door has been closed for weeks. Young Mike shut himself in and shut out his helpless father, mother and sister. Mike wasn't sick, but he just made up his mind not to set foot in the outside world anymore. In Japan, such young people are called "dormant people". This kind of behavior is also gradually spreading in western countries. His family had no choice but to stand in front of the closed door every day to wait, ask, get angry, despair, blame, ignore and expect.
