I wish the original Yu-Gi-Oh series had a slice of life episode. It would be super cool to see how Yugi and Atem worked out the day to day awkwardness of sharing a body like:
-Yugi and Atem having radically different preferences in tastes and having to negotiate what they want to eat.
-Pulling minor pranks on each other when the other isn’t in control/paying attention (hiding things, changing whole outfits then denying said change, etc)
Yugi trying to use Atem as a way of cheating on tests. Atem always refuses and gives a lecture causing Yugi to always turn the test in at the very last second because Atem won’t shut up. Atem also has no idea what a Pythagorean theorem is and isn’t about to admit it.
-Playing dumb about who is in control just as a way to screw with their friends’ heads
-Is there some kind of truce regarding going to the bathroom/bathing/etc where Yugi is always in control or is it whoever is in control at the time?
-Atem lowkey trying to hook Anzu and Yugi up behind the scenes.
-Negotiating chores, or is Atem a freeloader?
-Trying to find lost keys/deck/whatever and running around frantically trying to find where they last put it.
-Getting into heated discussions over something asinine like how to fold towels.
-Weird quirks unique to each person that can clue you off to who’s in control besides tone and posture.
Atem looked out the window of his palace, his eyes scanning the dessert sand. Oh how he was bored. He so desperately needed some fun, some action, anything really. He missed being in the present with Yugi and everyone else. He sighed then took a deep breath and closed his eyes, listening to the sounds of the wind when suddenly he heard a knock on his chamber door. He raised an eyebrow and commanded in a deep tone.
