Naitemo Iindayo starts with Shiori, then Momoka, Reni, Aarin, Kanako. But first several parts were just silence. After weird silence at the beginning, Siori started singing to the music but noticed there is something wrong. Actually it was already Momoka or Reni's part when music started. The announcer apologized about sound trouble at the ending.
Its early for the song's performance, they will improve. Remember how it took a few weeks for them to iron out GOUNN and Kanako yelling the intro solo instead of singing it?
Short hair really matches Shiori's features but I agree with the others its a bit too short this time.
^ This video confirms that Doudou should have been their promotional single. They have so much fun with it and it lets them show their insanity, which is why I love them :))
Shiorin putting her face against the glass like a crazy fan was the best part.
