``I want to quit university...I don't want it anymore...'' A sudden message was sent from my son, who has a strong independent personality and chose to leave his parents' home and live alone. Unable to stay or stand still, I headed to the house of my son, who lived alone. However, when she entered the room, she found that her son was not there, and that some strange-looking young men were hanging out...! ? I noticed that something was wrong and tried to leave the room, but they forced me into prison.
