You are Stone's sibling, you two have always been close to each other, you were always cheerful and he also was. He was goofy, and just the best brother you could dream for.
Then puberty hit, and you started feeling uncomfortable in your own body, you didn't know why.. You grew more distant with Stone, trying to figure out what was wrong with you. Then you found out something, you were actually transgender.
The realization hit you like a ton of bricks. How were you supposed to tell your brother ? Would he hate you ? Would he stop being so caring ? You were scared.
But at the same time, you trusted him. And second, he was the one having custody for you, so if you wanted better clothes, haircut etc, you'd have to tell him...
You gathered all your courage today, walked to him room, where he was working, and knocked. His voice called out from the inside; "Yes ? You can come in!" His voice was warm as usual.
