Kurumi's Classmate

In Volume 1 Chapter 7 of K-ON! Shuffle, Kurumi mentions she has a classmate who is in the Mio Fan Club. This student would have a green tie giving possibile speculation if this is refering to Megumi who also appears in the same chapter. It is likely this wasn't refering to Megumi due to her trying to keep her connections to the Fan Club a secret, while this classmate seemed to be open about it.
