A wife for Slenderman

Jeff has Nina. Tim has Toby. Laughing Jack has Laughing Jill. Slenderman has no one. He has always been alone.
Sally and Mila {my OC} {She is Tim and Toby's daughter and in this fanficion she is six} storm into Slenderman's office on a rainy day and see the stuff in his office.
The adorable six-year-old doesn't see a picture frame of a possible love of his.
She decides to find true love for Slenderman along with Sally. But....if searching doesn't help...then what?
