The physical and mental journey of young girls during menstruation. Menstruation is a metaphor for this cycle by the train. Flowers that show a bud state will regenerate countless times, each time. Flower picking is a sign that the girl is ready for the start of her period. The cycle of the girl's physical and mental state will be repeated every month. They all will come again, the monsters of pain's embodiment, the fear of self, and external pressure.
