^ Not sure what tameguchi is. Is it the less formal speech amongst friends? I wouldn't know anyway since I barely understand Japanese. I believe during Inoue's first SHOWROOM that they (Sayunyan and Waka) called up Rena. Then on Rena's next SHOWROOM she dialed up Sayunyan. It was perfect symmetry. And I think it was a really casual conversation. Looking through the Nogi SHOWROOM thread this happened on July 20, 21. Because Rena is our Nogi SHOWROOM queen I wonder if she has dialed up Sayunyan again. They should do a show together!!
