Nana, who works for a major railroad company, acts as a decoy against molesters and cracks down on them. Nana caught a molester who came carelessly that day. There she meets a young man, Kazuo, who came out as a witness. She is impressed by his justice-filled actions, but the last word she said, "I like molesting too..." caught her in her heart. A few days later, Kazuo, who I met during her commute, suddenly groped her crotch. Although she resists her sudden act, her body gradually heats up contrary to her feelings.
