Someone made a summary of the Gold Rush mini event.
>Pikarun had told Komino about her knowing Gomae in the past . And one of them cried on the train when they learned they'd sing GMW. I think it's Pikarun but could be Komino too
>There's a live motion of Kotone singing Gomae
>The choreography for Kachidoki was just like the one in the manga
