I just finished watching Arthdal Chronicles so now I'm craving for dramas where the main leads share this strong connection/love with or for each other that nothing can seem to break them apart

It can be mix with fantasy elements similar to usual chinese dramas where leads are already predicted to meet/fall in love w/ each other (e.g. Eternal Love)

Or can be any dramas in general that made you feel like the couple could stood the test of time (e.g. they met when they're young but still found each other/even if they were "reincarnated", they would still find each other).

as much as possible, i'd prefer dramas with: solid plot, intelligent/strong leads (esp female lead), and happy ending

optional: nerve wrecking but satisfying story buildup (e.g. Scarlet Heart Ryeo)

1. Rooftop Prince (time travel, historical/modern mix, reincarnation)

2. Queen In Hyun's Man (time travel, historical/modern mix, fated encounter)

3. The Eternal Love 1, 2 (time travel, historical/modern mix, reincarnation, diety)

4. Ashes of Love (deity, reincarnation)

5. Secret Garden (fated encounter, magic)

6. My Disciple Died Again (deity, reincarnation)

7. Goblin (deity, historical/modern mix, reincarnation)

8. She Was Pretty (met when they were young, fated encounter)

***Spoilers below***

9. What's Wrong With Secretary Kim (*spoiler: met when they were young, fated encounter)

10. Her Private Life (*spoiler: met when they were young, fated encounter) 

Honorable mentions: Unexpected (travelling into a comic book world), My Love From The Stars, Moon Embracing the Sun
