What You Came As

Your friend Aracy brings you as her plus-one to a Halloween party in a hidden Tower, where every costume comes true when the clock strikes. She came as a dryad, so now she's part tree, and her leaves turn red every time she looks at you. The witch hosting the party knows exactly why. She swore not to tell, and she's arranging your whole night anyway, in rhyme. Optional romance. All genders welcome.
