I thought I'd give this drama a try since so many people seem to enjoy it, but was extremely disappointed with the quality, so beware of the hype and set your expectations appropriately. I fast forwarded through the majority of this drama.

First off, production value. This is a very low-budget drama, so if you're coming to it from something with beautiful costumes, sets, props, and cinematography (like Nirvana in Fire, Rise of Phoenixes, Ten Miles of Peach Blossoms, etc.), the change is quite jarring. Much of my enjoyment of period/costume dramas is in the beauty of the costumes and settings, so I was already skeptical of the drama from the very first scene.

Plot-wise, I thought the premise was actually quite interesting - combination of time travel and sort of dissociative identity disorder - but in terms of why and how and what happens, I found the story execution kind of nonsensical and the plot goes way off the rails.

Characters - I know some people appreciate that the FL is feisty and independent rather than some kind of wilting flower, but whether due to writing or acting, I found her unlikable and too over the top, though I did appreciate how the actress portrayed 2 different personalities. I didn't like the ML all that much either. Or anyone else in the drama, come to think of it. Again, not sure if it's due to the writing or acting or both, but I found all the characters to be either too flat or too over the top.

At the end of the day, unfortunately, I couldn't suspend my disbelief that this was more than just actors on a set saying lines that someone wrote.
