The Sun in the Dark

Both leads have meet in multiple lifetimes that always end tragically. Both FLs have a dangerous, powerful identity inside them that ultimately takes over. Both MLs are demons in their current life, but not in the past ones. Both have "good" sects who actually do horrible things.

Both are xianxia dramas in which the MLs are demon lords, and the FLs immortals who have a past life connection to the ML. Both SMLs are the FL's master who she is devoted to but has secrets of his own. Both plots have the FL thinking the ML betrayed her and later discovering the higher immortals are manipulating her, pushing her into killing the ML as she did in the past.

Both dramas have a "nighttime" deity ML (Night vs. Moon) and a FL who has some sort of curse (blood vs. seeing ghosts). Both dramas have a similar feel and characters.

The opening scenes are so similar you can’t help but wonder if it’s a rip off of the save story. Except that the girl wants to kill the night deity in SD whereas the FL was thankful for his help in MM…

ML’s character reminds me very much of Xu Feng’s demon lord persona. Same vibe, sake pining after the FL, between love and hate, and having a complicated past .

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.

- both worlds have same aesthetics
- both couples are connected with same thread of fate/something
- both have the same dynamics super strong male leads and with hidden power female leads
