Mr.Sketches's Links
Sketches was only supposed to be a fuckbuddy and Liam fell hard anyways. If this is what Sketches intended, he doesn't know. He just knows he found it difficult to tell the demon that this was the case (because confessing your feelings is obviously more intimate than having sex).
Curse KNOWS Sketches doesn't like him and, like any sensible person, keeps out of his way when he visits. The last thing he wants is to give him a reason to voice his dislike any more than he already does.
