In the middle of the night in Mondstadt, walked a young boy.

Kaeya Alberich, a boy of the age of 12 who hadn't lived much of a life.

Or, a normal human life.

It was a beautiful, rainy night in Mondstadt. The wind blowing in harmony with the rain.

But, Kaeya was alone in the rain. It pouring down on him like a mysterious hail.

Poor thing.
