Come to me, Lucifer!

Summoner AU: Alastor out of curiosity for the knowledge of what the King of Hell is like. He seeks answers and stories to bring another world to his listeners and to a new audience he hopes to capote by writing a romance novel based on the stories he would hope to learn. However, with each meet that passes by Alastor seems to become too attached to the King in ways he never believed possible. Lucifer on the other hand, felt that this human was different from others, stange and also a bit creepy-but when he feels his marriage crumble, it's this very human he seems to find comfort in. Through life and death the two bond, but at what cost?
