In a time-travel novel, the heroine is a modern squatter with a good family background. After graduation, she hid in a rented house, ate and slept, played games when she woke up, and ordered takeout when she was hungry. She seldom went out when she had nothing to do. When she ran out of money, she went to work as a temporary worker to earn some pocket money and then continued to stay at home. This squatting lasted from 19 to 32 years old. According to us, it's called otaku culture.
