The Sun in the Dark feels like a low-budget remake of Love Between Fairy and Devil, but is still different in some ways and very fun to watch. In both dramas...
- The FL has an unknown identity and is underestimated in the immortal world;
- The FL hides the demon lord in the immortal world, and is later brought to the demon world;
- The ML is heartless at first, but protects the FL;
- The FL and the ML are bound by a spell/artefact;
- The 2ML is a high-ranked immortal.
