The story of runaway girls repeats the same tragedy across eras, and this trend continues in modern-day Reiwa Japan. Among them is Yumeru, a teenage girl who ran away from home after a fight with her mother. With nothing but her smartphone, she meets an older man with a lolita fetish through the internet, who quickly approaches her. To her, his offer seems like a lifeline, and she naively agrees to go with him. However, he treats her merely as a plaything, easily taking control of her body. This scenario symbolizes the dangerous nature of today's online world and the malicious intent lurking behind seemingly innocent interactions with vulnerable young girls.
