Dream never knew Error personally. Very few did. When she learns he's more than the God of Destruction, when they start to hang out and really get to know each other, things take a turn no one would have expected. Things especially go down hill as both Dream's and Error's friends get involved - another layer of drama and relationships to sort through and repair. \=/ !!DISCLAIMER!! All events in this story and the plot belongs to @trashy_name. This is a rewrite of "❤Insomnia❤" by them. I do not own the characters, they all belong to their respective owners. !!WARNING!! This book contains: SWEARING, MILD SEXUAL THEMES, A LOT OF DRAMA, SEXUAL HARRASSMENT, AND USE OF/MENTIONS OF ALCOHOL. ((Cover by me, art to original artists))
