"My husband is away on a business trip, so please come visit me once in a while," his aunt Mizuho (Mizuho Kaito) contacted Toshio, and he couldn't contain his excitement. Mizuho was his childhood first love. Toshio never imagined he'd be able to spend time alone with her... He walked lightly to his aunt's house. Mizuho, ​​whom he hadn't seen in a long time, was still beautiful and charming as ever. However, the emotions that rose up when he saw Mizuho were completely different from those he had felt as a child, and Toshio himself was confused. An intense lust welled up inside him when he saw Mizuho's face.
