Two women with blue hair are standing in front of a painting

A cover with a background in deep blue tones, which conveys a sense of mystery and emotion. In the center of the cover, you can represent the two protagonists of the story. One of them, the blue-haired girl, might be looking out at the horizon or through a window, with an expression that reflects both her latent rage and vulnerability. The other girl, the author of the anonymous notes, could be looking at her from a slightly different angle, with a look full of complicity and affection. You can add symbolic elements that represent correspondence through notes, such as crumpled paper, envelopes or letters flying around the girls.
