Phone calls keep pouring in, inquiring about Aki. News has spread that Yui and Aki will be doing a collaboration. Yui is not pleased because they were not even consulted to begin with. But Aki says she's okay with it. Yui tries to dissuade her since she knows Aki is not used to such things that Yui is doing (dressing up in "cosplay," being bombarded by cameras).
