"Youth" is a weird box store where you can't buy what you want no matter how much money you spend. But every customer who steps into the store will take away a box in the end. This box does not contain jewelry or clothes. It is only used to store... Our memories.
The upper-class people who enjoy a luxurious life, the good young people who are full of ideals and strive for progress, the gangsters who hang out in nightclubs and get drunk... Regardless of social class, regardless of height, fat or thin, everyone is a guest of "youth".
