This is Our Ouran Fair

The Host Club must race against time to keep Tamaki in Japan and save the club from disbanding. However there are a few bumps along the way, as well as a wild horse ride, fighting with Ootori family police and Grand Tonnerre taking over lots of businesses. After Hikaru gets hurt, Haruhi rides the carriage and runs after Tamaki. Haruhi convinces Tamaki to return to the Host Club and reaches for his hand, but Tamaki is stopped by Eclair Tonnerre. Haruhi falls from the carriage and off a bridge. Eclair lets go of Tamaki's arm and Tamaki thanks her before jumping from the car to save Haruhi. In the end, Haruhi, dances with all the members of the Host Club.
