Three beautiful daughters grew up in a dog and cat care clinic. The eldest was named Takako (Keiko Tsushima), the second was Tsugumi (Keiko Awaji), and the third was Mihato (Hibari Misora). Mihato was still a pretty seventeen-year-old girl, but she considered herself as mature as her older sisters. Mihato knows that Tsugumi is friends with Ippei Yaguchi (Masao Wakahara) and acts as a love messenger between them, but she didn't know that Takako is also in love with Ippei...
