Out of the nine "original Hallyu actresses" unfortunately she and Han Ga-In (where is she now?) are often regarded by Korean fans as the ones with the weakest acting.
Song Hye Gyo was also considered the weak link of that group of that nine actresses up until The Glory ....

It has only 8 episodes so there may be something to that theory.

Given the shorter length, the premiere better be on point.

After HI BYE MAMA finished, I recall an interview KTH did about her comeback series. She said that she felt guilty doing the drama because she was away from her family. I found the tone to be very sad since clearly she enjoys acting. She may have agreed to this series because of its length and 1/2 the shooting time.

This has only eight episodes, because everyone, especially the FL, moves in slow motion. If everyone moved at normal speed, this would be two hour max.

Plus: the FL need A LOT of time to process things, because although they look normal, someone seems to have sucked out their brain. If they did not look to polished /alive, I would think this is a Zombie movie.

I am totally annoyed.
