Alquimia das Almas 2: Luz e Sombra (2022)

It has similar storyline.
- Female leads with amnesia, were somehow involved in marriage of convenience with Male leads.

i don't know if this is helpful but there's an amnesia subplot in both that was dragged out endlessly and then everything wrapped up in a rush

But on the night of their wedding ceremony, Eun Soo's father passes away. And soon after, Chang Ho disappears too! In the blink of an eye, the two people Eun Soo loves most in the world have left her.

Both are fantasy and Rom-com genres. Both have a similar theme about a soul ending up in a different body.

Taner tries to commit suicide and when she wakes she finds that there is another soul in her body. Xiao tan's soul entered Qu Taner's body. In the end, Qu Taner left the body for Xiao Tan.

Both are high fantasy genre Korean dramas written by Hong Sisters. Hotel Del Luna is modern, AoS is historical fantasy. FLs are used to be assassins before.

Both are historical dramas situated with fantasy;
Both have moon/sun archetype;
Amnesia female lead with unhinged male lead;

Fantasy and supernatural themes, Complex world building, Romantic Subplots, Strong fateful characters, Royalty and Power, Visual aesthetic and cinematic style, Strong female leads.
The blend of magic, destiny, romance, and intricate world-building makes both dramas particularly engaging.

- K-dramas
- Good swordmanship
- Beautifully shot and well acted
- Many characters
- The plots themselves probably won't have much in common.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide
