He is letting her stay in his house for free in contract because of pay was only twice of previous salary not thrice, but in next scene he is asking for room rent. Bad script.
No continuity.

Dropping @ EP4 with 6 Star.
This drama had potential but has bad scripts.
Characters are created with good personality which are relatable.
But their chooses does not make sense.
By 4th episode you would notice FL is empathizing with ML who cause her father to faint then her father.
Also Long time friend of ML and lawyer does not give any proper advise about employee layoff and any other activities he does.

She is annoying and dump from the beginning, but we don't see because of how other characters are behaving.
By 5th episode you would notice she is empathizing with ML who cause her father to faint then her father.

And Eliza's acting is too stiff.

Base story is very weak.
Also i don't understand why all of them chose to go for training, where as only 3 of them wanted to go for it.
Saying i want to beat that person work only for FL.

From https://en.wikipedia.org/wiki/Science_fiction
Science fiction is a genre of speculative fiction that typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life.
It means you use your own imagination for possible (Note possible) alternates of our own reality. If it becomes impossible then the genre become fantasy. You can not bend reality and call it Sci-Fi.

You just described it as Sci-Fi, then how can it be without science?
Fiction is meant for pure fun but Science should have some reality.
Why do i mention is that when you watch fast paced Sci-Fi Movie/Drama these kind of small mistakes takes the fun out of watching.

After EP30 story is all over the place.
Scenes/Scenarios/Timelines doesn't match at all
3.5 Star

She gave it to him before her staged assassination.

I really don't understand physics of this drama.
There are lot of unnatural physics happening.
To name one on EP4 ML is generating electric from his body (that is how it was shown) person closes to him does not get affected much but people who are standing 5 feet away are knocked out. How?
FL head is healed within two days.
FL head injured more than 15 time yet she is not hospitalized.

Also her head is healed which had 13 stitches in just 2 days. Is this series happening in different world where physics works differently.

Is FL's head made of iron or what.
By EP4 she was hit in the head by at least 20 times, she should have been hospitalized.
Also why she is empathizing with ML who is directly responsible for her parents disappearance.

The body was replaced and put in well. If she is dead their no need to switch. She must be alive and kept prisoner.

on Viki

Dropping at @EP3. 4Star
First thing you need to do is learn his/her personality if you are going to impersonate.
How in the hell FL supposed to do that with no guideline.
If anyone with enough brain who sees her daily basis would know she is impostor, like ML who already met her more than once.

unbelivable back story of Cha Hyun Soo

And don't forget disable man who may/may not know about cars rebuilding van out of nothing in less 3 days.

@EP6 Also what is the point of interrogation by military?
Either they already know what is happening or the don't.

accidentally i skipped ep 4, didn't realize till end then looking for 8th episode.

Story, Cinematography, acting, direction, casting all excellent.
But i give 3*.
It has too many inconsistency.
Timeline never matches up with each individuals.......at all.....
