Being a teenager is hard! How are you meant to navigate hormones, crushes, annoying family and schoolwork? But Jay’s got it even harder: joining a new school and trying to understand their body as they go through puberty as an intersex person. Luckily, they’ve got the support of old friend Sera, and a burgeoning new friendship with popular boy Wooram. But as hormones rage, the trio’s friendship becomes a very messy love triangle. Who will Jay choose and does who they’re attracted to dictate who they are?
