Therapy for the Dark Lord

If you like revenge and underdog rise stories you can follow one-handed, Therapy for the Dark Lord is built exactly for that: a 9:16 series designed for mobile. Like most vertical dramas, it moves fast: short episodes, a cliffhanger at the end of each, and no filler. The plot, in short:

Modern psychologist Vivian transmigrates into a fantasy novel as a doomed side character. To survive a deadly inheritance plot, she tames the dark-magic Duke Lucien and heals his childhood trauma. Together they crush the schemers and expose the royals' human experiments. The world-ending monster, redeemed by love, becomes her guardian.
