Komori Emi (Mimura), an elementary school teacher in Nagoya, is a dowdy woman in her 30s. She cannot say what she wants and is making no headway in her job, romance and life – looked down by her students and dumped by her fiance. Her only comfort is Twitter and SNS where she gives vent to her complaints anonymously and takes solace from the replies. One day, Emi receives a rant from a mysterious man called Yaegashi Shuji (Kakei Toshio) in response to her comments. “You are only a fly buzzing around a fan. Listen to me if you want to change your life.” With some objective in mind, he instigates Emi and gives her various “missions” that would change her life. Emi is twisted around by him but gradually transforms into a magnificent woman.
