The Everlasting Sisters

One day 7 years ago, twins were born into this world. Their mother named the first one Everlasting Grief, and the second Everlasting Frost. You wouldn't think they are twins due to their diffrent looks and personalities. Grief was colourful, eventhough her name suggest she would be gloomy and bland.
Her eyes were filled with pain tho she has never had experienced any.
Frost had washed out colours and was more defensive of what was her's because she was never the favourite of the two, their mother never liked Frost as much as Grief.
