Luna's roommate, Halie, has recently scored tickets to see one of their favorite bands, Avenged Sevenfold, along with backstage passes. What will happen when Halie hits it off with Matt and Luna ends up having to hang out with the band more and more?

[I do not own A7X or any of the members, but I do own Luna and Halie and this storyline.]
