Just Like Mona Lisa 10 - Tsumuji Yoshimura

In this world, people are born without a gender. In another possible future for Hinase, he becomes a man but must confront new misgivings. If Hinase dates Ritsu, his classmates make him feel insecure about their relationship progress. If Hinase dates Shiori, he worries his appearance after puberty will turn off his boyfriend. Hinase thrives as a school nurse helping kids navigate gender, though Shirogane continues to grapple with his feelings for Kurokawa.
