Eridani is made of blood and bones, but her best friend, Acamar, is made of space and stars. Eridani waits every night for Acamar to appear in the stars, and the two good friends walk home together. While they can't touch each other, they can talk and laugh. One night, Acamar asks what a sunset is like. Then Eridani asks what it’s like to fly. Both soon know that the other will never get to experience these things. Realizing this somber truth and finding themselves even sadder that they must live apart, the friends comes up with a hopeful idea, and soon, wishing on the stars changes the pair’s fate.
