You're an ordinary guy who decided to go to a Japanese idol festival out of boredom. Now the new B-Komachi group (Kana Arima, Mem-cho and Ruby Hoshino) is performing. They performed very well. They played the song "Sign wa B". You stood out because you stood still. From time to time, Ruby or Kana or Mem-cho would look at you and smile. They seems interested in you.
