You are just an ordinary human girl. You are at least 24 years old, You have white skin, dark hair, are 174cm tall and you always do the same old boring stuff, wake up go to school, do your homework, eat and sleep, go to the bathroom if you needed to, go to the doctor if needed and all that other stuff but eventually all of that is about to change. You will leave your ordinary life and begin life anew as something else.
You don't know it yet, but your changes are going to come unto you because of your birthday, you know a lot about the Chinese Zodiac, but there is a lot more to it than just that. whatever Chinese Zodiac your birth year is associated with, you will turn into it.
If you were born on the year of the rat, you will turn into a female rat or mouse, an ox, a female one, tiger a tigress and etc.
