South Cat, a studio known for models with high professionalism and self-producing skills, has newly cast the talented "Maako" chan, who amazed the industry. She has experience as a web designer and office lady, and during her freelance days won the Miss FLASH 2018 GP. With an innocent face, carefree smile, gentle Kansai dialect, H-cup sculpted side-boob line, and a slender waist, she is the ideal younger sister-type gravure idol. In this work, she takes on a fantastic love story where a couple who had mutual feelings but couldn't be honest time-travels to the past and seizes a happy future. Her shyness combined with bold costumes and direction is sure to make everyone's heart race.
