Haruhi's always had a talent for telling twins apart. Her first set wasn't the Hitachiin twins but the Furuya twins, Tsubaki and Hinata, who had to move away. Now they're back and enrolled in Ouran, but they aren't so 'identical' anymore. More like polar opposites, really. Tsubaki wants to go back to how they were, and Hinata can't let that happen. Canon couples, and twinsxOCtwins.
