In which ANY combinations of Maes Hughes, Roy Mustang, Gracia Hughes and Riza Hawkeye is welcome. The foursome is particularly loved.
The Contest Where the Rules Are Made Up and the Points Don't Matter.
There are two possible ways you can enter the contest. Or three, 'cause we're all about the combinations around here. You can choose to enter on the Lyrics side of things, or the First Line side of things. Or, if you're feeling really brave, both. If you want both (because after all, isn't the whole purpose of the OT4 having your cake and eating it too?), you have the option of either writing two separate fics, or using the prompts for the same fic.
