That Prince Is A Girl: The Princess And Her Grand King

MoboReels released it as 61 bite-size episodes mixing fantasy, made to watch on a phone in one sitting or a few.

Watch it for a world with its own rules and a lead who learns to bend them.

The whole series takes roughly 1–2 hours, so it's an easy binge.

Start from episode 1 below; autoplay takes you to the next episode when one ends, and nothing needs a sign-up.
