Synopsis
In this world, every person is born without a gender. Upon turning 12, their bodies change to match the gender they wish to be. The only exception is Hinase Arima, whose physique remains unchanged even as they reach their 18th spring. Still, Hinase is content as long as they have their two childhood friends: the bubbly and adorable Ritsu Kaga, and the tall, headstrong Shiori Takayama. As their final year of high school approaches, Hinase assumes life will continue as usual. That assumption is quickly overturned when both Ritsu and Shiori confess their love to Hinase on the same day! Having never felt romantic or sexual attraction, Hinase is at a loss for how to reply to either confession. Time is pressing, and Hinase must soon make a decisive choice: whether to become a boy or a girl.
