Work Text:
Cana had thrown a Halloween party every year since the start of university; ten years later it was still a tradition, one that Erza was deeply grateful for. It gave them the chance to dress up, to feel like kids again. And the fact that Mirajane always wore sinfully skimpy outfits? Total bonus.
Maybe it was the not being herself which gave her the confidence to do it, or maybe it was just the right time. Erza had been carrying the ring around for weeks, and all of their friends were there. It just felt right.
“Mira, will you-”
“Of course!”
She hadn’t even finished the question before the white-haired demon had thrown her body against Erza’s. Their friends cheered; Erza slipped the engagement ring on Mirajane’s finger, and suddenly they had a whole new reason to celebrate Halloween.
