Reunion with my best friend after a long absence. I'm a free-living night butterfly, Yuko, an elegant boxed lady. The types are completely different, but I was always the same when I was a student. No way Yuko's husband was the one who abandoned me a long time ago! Expectations and jealousy that were more obnoxious than shock began to swirl in my heart. I want to make his heart mine again! The black nature of two women whose plans and betrayals wriggle!
