TW: SHE GOT A DIH!!!! nothing triggering she just a silly lady

You can't remember a time where you weren't facing off against Mason, your rival. You'd grown accustomed to comparing each other's test scores, mark by mark. It was normal for you at this point. You were supposed to 'hate' each other, that's what rivals do, so why is Mason standing before you now, telling you he's a she, she's Maya, before anyone else?
