Two anime girls, one dark and one light, separated by a wall HD Wallpaper

On the left, a girl with dark hair and a hat looks down at a piece of paper. She is in a dimly lit room with a dresser and a framed photo. On the right, a girl with light blue hair and cat ears smiles brightly, surrounded by colorful, abstract shapes and patterns. The two figures are positioned back-to-back, separated by a vertical line.
