I'm the Real Heiress, Not Her

DramaWave released it as 60 bite-size episodes mixing billionaire, made to watch on a phone in one sitting or a few.

The draw here is the hidden-wealth reveals and the people who misjudged the lead.

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.
