Written as part of Kris 'n' Good Books' 'choose your own m/m story' challenge. This is now hosted by Goodreads' M/M Romance Group.
The story prompts for the author were:
the setting ~ a stuck elevator
some background to the main protags ~ one of them sings when he gets nervous
another character ~ an inebriated priest/minister/whatever
a conflict ~ they had a one night stand but one of them can't remember
an object to be mentioned in the story somewhere ~ an ice sculpture
