Not sure how to begin the review for this drama because everything is just average in this drama, the comedy elements stems from the emotional and physical pain exchange between the ML and FL. But its just too far fetched a concept. Some efforts have been put into the mma fights, but its clearly not convincing.

The straight faced emotionless kris fan is just painful to watch, because that is really not his type of genre. judy qi as a mma fighter is also not convincing. Chemistry between the ML and FL is average at best even thou they have alot of skinship and kiss scenes.

Its also the usual bossy CEO ML and dumb FL combo, but without high chemistry and hook for the plot, this is just a tough drama to like or anticipate weekly.

So to sum it up, I can only think of the following reasons to watch this drama.

Reasons to watch this drama:
Judy qi or kris fan as main leads if you are a fan
MMA theme
Soul exchange theme
Revealing outfits because of mma?
Only good as a filler drama if you have nothing else to watch.
