Nakayan was one of the 13,000 people who entered the 3rd Generation AKB48 audition in December 2006. She passed the audition and debuted with Team B on stage in April 2007. She was moved to Team A following the team shuffle in August 2009.
Since Nakayan entered AKB48 6 years ago, she did not rank within the Top 40 in any of the 3 Senbatsu Elections. In the autobiography she describes her feelings regarding the situation, and how she managed to eventually look at this and find it "amusing".
Even without being a Senbatsu member in AKB48, Nakayan has already distinguished herself through voice acting for an animated version of Moshidora, as well as Neptune MK2, a role-playing game on Playstation 3. She will also be a voice actor in AKB0048, an animation about AKB48 in future.
The book also describes the difficult life of an Idol behind the scenes, and how Nakayan was able to find a comfortable place for herself after overcoming the hardships. The central theme of the book is "Send a positive message for all the 'Non-Senbatsu' people in real life".
