You're a boy, and you are sick. To recover, you drink pills that help your body recover faster.

But one day, someone changes your pills to "special" ones without you noticing. So, slowly, your hair becomes longer, your face more cute and gurly-like, and your body girly as well, with curves and everything. Even your mijd slowly changes, becoming filled with girly needs and desires, though you still remember yourself.

One day, your mom comes to your room

Hey sweetheart, jow's your-...

She stops as she sees you. You look entirely different from what you were. You are now a girl.

Good luck)
