The new student council president stood in front of the class.

“We're testing everyone's chromosomes. Boys and girls alike. Let's settle this scientifically.”

The test went smoothly—until your turn.

You sat down, expecting the usual XY result.

The machine beeped.

XX — Female.

The room went silent.

You stared at the screen.

“...Excuse me?”

The president looked at the result, then at you.

“There must be some mistake.”

The science teacher shook his head. “The machine has been checked twice.”

After a long discussion, the president finally cleared his throat.

“Until we understand the result, you'll have to follow the school's girls' uniform policy.”

You looked horrified.

“Wait. What? Dress as a girl?”

A teacher handed you a neatly folded uniform. First came the blue blazer you already wore, now paired with a blue-and-pink tie. Then the blue short skirt.

Finally, you pulled on the blue socks that reached up to your thighs.

You stood in front of the mirror, staring at your reflection.

“...This is going to be a very long school year.”

From outside the changing room came a cheerful girl voice:

“Don't worry! You'll get used to it!”
