Is puzzleshipping a canon

Most of it is all a matter of opinion but in some cases yes it is canon. The two characters spend more time physically touching one another (holding hands, hugging) than paying attention to the other female characters and Yugi tends to get this look in his eyes with Yami but not with the other yugioh characters. They also tend to have more faith and trust in one another. In on of the episodes, Yugi sacrificed his soul for Yami when playing an oricalcos game.
