Since ancient times until today, many young girls have been forced to run away from home over trivial matters, often impulsively fleeing without thinking about regret or the future. Not uncommonly, they easily fall into the traps of strange men, forgetting hunger, rain, and cold. Among them is Yui, who ran away after a heated argument with her mother. Wandering alone and starving, she met an older man by chance, and perhaps her heart felt slightly comforted by his words. Yui ended up living with this man, beginning what might have been a new life for her.
