Aha...hmm, well I'm glad that they didn't put that in the drama. Touko never seems to be the slightest bit of interested in Aniya after all so it would have been totally coming out of the blue and confused the living hell out of me^_^
No seriously I loved the Aniya/Touko interaction but it was the adorable friendship and teasing I liked (Their first interaction was completely and utterly hilarious-XDDDD!!)
