Narita, a family restaurant employee nearing thirty, spends his days buried in work. One evening, feeling dejected after a failed job interview, he absentmindedly watches a recommended video over dinner. On screen is a cool, slightly cheeky artist named Sasa Yozaki, whose overwhelming talent and vocal prowess captivate him instantly. Later that night, a mishap with his laundry leads him to a run-down coin laundromat—where he catches sight of a woman who feels strangely familiar. She looks just like the singer he was just watching online… because she is Sasa herself.
