Happy Birthday Sir Arthur Conan Doyle, sorry that character you hate is what you’re known for.
shipping is NOT purely about sex
shipping is NOT believing two characters are already in a relationship
shipping is NOT wanting the show/book/movie to be purely about your ship
shipping is NOT automatically ignoring the actual overall plot
shipping is NOT a game
shipping IS, however, personally interpreting two characters’ feelings for each other as romantic and wanting their feelings to come to fruition so they can be happy
