Aelithia Returned as a Goddess

Aelithia, born with a rare divine core, was framed by her stepmother Vessela as a curse and thrown into a forbidden abyss at age seven. For seven years she trained in secret, reforged her core, and returned to destroy the Malister family and the Archmage Council. She ended the dark reign with divine power, achieving revenge and redemption.

DramaBox released it as 70 bite-size episodes mixing revenge, fantasy and secret identity, made to watch on a phone in one sitting or a few.

The draw here is the slow build to a payback that lands hard. On top of that: a world with its own rules and a lead who learns to bend them.

The whole series takes roughly 1–3 hours, so it's an easy binge.
