Dumped Him Crowned by Dragons

If you like revenge and underdog rise stories you can follow one-handed, Dumped Him Crowned by Dragons is built exactly for that: a 9:16 series designed for mobile. Episodes last a minute or two each, so you can watch a few on a break or binge the whole story in one evening. The plot, in short:

For seven years, Veya hid her identity as the Abyss Dragon Queen and used her power to raise her fiancé, Leon, to the top. But he betrayed her for another woman. He never knew she was the Dragon Emperor's long-lost sister and ruler of the Seven Dragon Realms. Now she will take back his title, fortune, and glory—and make every traitor kneel.
