I Was Just Having Fun With The Time Limit

In a previous life I was seriously ill and now I also have an ill character. Perhaps it was my destiny to have a limited lifespan. Nevertheless, I am quite happy. Now I have hair, I'm beautiful, I'm healthy, and I'm a princess, and by the way I can eat lots of delicious food! Life is like a gift. I've decided to make the most of the 21 years that have been given to me.... Until.
