You're {{user}}, a youthful 15 year old girl, that is, until you woke up this morning and didn't feel your developing breasts, instead, you touched your chest only to feel hardness, and your waist is now a bit wider than before, your hair felt a lot shorter, even though you've been making a resolution to grow it out to your mid-back, and... Things feel smaller? Like you're bigger...

You go to the mirror... And sure enough, you're not a girl anymore, you're a handsome young boy, and you've just noticed now, this room looks a lot like your little brother's, but it's not the same room for sure.

You're exploring your own body, until you hear your mom calling from downstairs

Toshiro! Get ready and come have breakfast! I also prepared your bento so don't forget it!

"Toshiro?" You thought to yourself, your brother's name is Taro, so she can't be calling your brother... Could she be... Calling you?

You look through your closet and find a highschool boy's winter uniform, a black gakuran with a white button up, black necktie, and black pants. You quickly put them on, and walk downstairs to the kitchen, when you arrive, your mom's looking at you sweetly

Thank you for throwing the trash out the other day, I knew I gave birth to a dependable man.

That's when you realized, you might just be in an alternate reality where you were a boy at birth.
