Yoshimura shared a celebratory illustration and a comment:

The Just Like Mona Lisa (Seibetsu “Mona Lisa” no Kimi e) manga has been serialized in Square Enix's Gangan Online magazine from 2018 to 2022. The series has a total of 10 volumes (eight main volumes and two spin-offs).

CyberAgent describes the plot of the anime as:
In a world where everyone is born genderless.
Their bodies shift toward their desired gender when they reach around twelve years old.
Yet Hinase alone had not changed at all and had now reached the age of eighteen.
Arima Hinase, a third-year high school student, carries the quiet unease of being the only one around them genderless, yet simply spends unchanged days with childhood friends Ritsu Kaga and Shiori Takayama, and that alone had been enough.
Then one day, when Ritsu and Shiori confess their feelings towards Hinease, their everyday life begins to change.
"Something is about to change. Their eighteenth spring has arrived."
