Ran questions if Shinichi liked her at that time already as much as he does now. Conan also starts remembering the day back when Ran and him, as Shinichi, visited the place... Shinichi was waiting for Ran inside Beika Aquarium. Ran was late. She tells him that she planned to invite her mother and father to visit the Aquarium for a romantic situation.
