Four Supreme Guardians of The True Heiress

NetShort released it as 24 bite-size episodes mixing billionaire, made to watch on a phone in one sitting or a few.

Watch it for the hidden-wealth reveals and the people who misjudged the lead.

At about 29–53 minutes in total, it's quicker to finish than most full-length series.

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