Impossible to ship Shinichi with any character other than Ran

Shinichi and Ran are perfect they start with something very basic like okay just childhood friends but when you watch the anime you see how deep their connection is and how much they love each other like Ran has been waiting for Shinichi for all this time! Type?? She is wonderful and Shinichi never thought of any other girl other than Ran, he never had any doubts that it was her and even better he fell in love with her cute smile, anyone who saw the anime knows that the two would do anything for each other including sacrificing their own lives So I can't understand how there are people who ship him with Haibara seeing that he and Ran are wonderful together and they're not even really dating yet
