Aoi Mizuhara, a slender married woman who met her husband through an online affair site. By chance, the park where they had their date was next to a small zoo, and the two enjoyed strolling together as if on a real date. She admitted she'd only ever dated men she met online and had little experience with real-life romance—her current husband was someone she originally met on the internet too. Living by the belief that as long as she was happy, the method of meeting didn't matter, her life took a sudden tragic turn when she discovered her husband's infidelity. That shocking betrayal planted the first seeds of temptation in her heart, slowly growing into a desire for revenge through her own affair.
