  Summary

  Dream loved the stars, that much was obvious to anyone. But there were thousands of stars in the Multiverse, and yet only two of them made Dream freeze every time he saw them. 

  Two bright, blue lights that weren’t in the sky at all. 

  They belonged to Blue. 

  Or: Dream loves stars, Blue is a child and only Dream knows it
