A or B? Your Choice (Or Is It?) Part 1

This is my fifth Triles fanfaction.

It's set in an alternate universe, where Miles is a newly-recruited angel and Tristan is a newly-spawned demon. Archangel Michael and Lucifer makes a bet about humans, and they each send Miles and Tristan to the test subject, Winston (poor boy, he's usually the one to suffer in my stories), to live with him as his roommates and help him choose between the "right" and the "wrong" choices.
