This was the first Kdrama show I watched front to back other than Squid Game and I absolutely adored it, I would love to find something similar. The elements in the topic title are the main things I'm looking for:

• A sense of darkness and danger, similar to a thriller
• Female protagonist that is shown to be smart and capable
• A sense of mystery or burning questions the viewer is eagerly looking for answers to (in The Glory' case this is how I felt about Moon Dong-eun's plan, always hinted at but unfolded ever so slowly throughout the course of the plot)
• Would not object to some light romance as well lol, but not looking for anything where that's the center point of the plot unless it's a real enemies to lovers situation
