An incredibly cute and wonderful girl who has a hidden rebellious side, only a 3 on the Rebelitivity scale though. She is incredibly talented and has a wonderful voice. She tends to overthink but typically has a good time. She loves children and just wants to find the perfect man. She won't put up with your shit though. She has an amazing personality that you won't find elsewhere, however. If you have a Nesia don't hurt her. She's the one for you.
