In which episode of Golden Time did Koko say "I love you" to Banri on the school staircase? There was a sequence on the school staircase where Koko said "I love you" and Banri fainted. Which episode was that?
Actually it was Banri that fainted not 2D-kun. As you can see, he's still standing on the top of the staircase. This happens in episode 7 at ~7:30-7:40
