Here's a translation of Nanako's blog post about that episode. Direct and real. She says she knows an idol has to be cheerful inside and out, and that she is basically a gloomy person. She thinks people may be wondering why she's doing this work, but says her goal is to be cheerful and she's working hard at it and hopes people will watch over her as she does. And I catch up with some of the things she's written and pics she's posted in her previous couple of posts.
