The world looked different before. Everything was gray and the days were all alike. There were even no seasons...
But the day she appeared everything was changed. She gave the world its colours, that we know today...
A that's how seasons came into being. The most colourful one was named after the girl with beautiful colours. Autumn.
A then there was a girl named Summer... and Spring... and Winter...
