This show should be a hit! I don't understand why it doesn't have so much exposure. The thriller is thrilling with so many plot twists. The story is really good. It doesn't even have a filler episode. The show pictures an agency office with such "problematic" environment. It seems to have messy conflicts, but there is the starting point where we will begin the enjoyable journey. It is boring up until Episode 4. But if you're being patient, you will get paid off!

Soul-swapping is not an easy thing, but both main leads deliver it excellently! Kim Ji-Eun and Lomon have to dealt playing as both characters, and it goes really well. During the soul-swap, I feel like they are actually switching—they become totally different person. I even think Lomon really can imitate Ji-Eun's gesture when he plays as Na-Eon.

The only thing that disturb me is the writer decided to give the main leads frustrating personalities. Na-Eon is a b*tch and ruthless person at the beginning of the show and she hardly have a character development, even after going through some big moments. Also being a thoughtful and ambitious person as Na-Eon, isn't it more reasonable for her to try protecting her body from the killer during the soul-swap, rather than throwing Eun-Ho in her body to some dangerous scenes? Eun-Ho personality at the beginning is the worst. He looks like an eight year boy trapped in the man's body, who reacts excessively at everything. Ji-Eun plays this well as Eun-Ho, but to think that she is "actually a man in a woman's body", it doesn't seem correct.

The intention to use this show as a media for Seongsu-dong tourism promotion goes in the right direction. I love the scenery of the Seongsu-dong view, and it really promotes Seongsu-dong as "Pop-Up Store District". I will really recommend this show!
