I totally loved how this drama built the the plot with the aid of the main trope. (Body swapping) I feel like they didn't over do it to the point of annoyance. The swapping in a way allowed each (mostly male lead for some reason 😐)
Let go of their scars,heal and grow.

The male lead was unexpectedly not annoying, he had a strong spine though he's really slow when it comes to Man-ing up and admiting his feelings. ( cowardly? Nope it's room for growth and through out the drama we see the change.)
The female lead's character is really well done with maturity (mostly) and the way she handled problems was actually for once kinda good. Both characters have their goals and motives each is really cleared out.

The Leading actors/actress gave an amazing performance though sometimes it did feel a little animated like. Loved the subtle and the big changes that each showed when the swapping has taken place. (To the details like how their voice sounds)

The side characters? Supports? each actor portrayed it well even though the supporting characters felt one dimensional (sadly) during the first half, the last half of the drama added depth to the characters to some extant making them feel more prominent. I love the way each had their moment. Those that I Innitialy disliked ended up becoming characters that I didn't dislike- wise words of dawn 2024 🐣

With that said the ending before THE ending (10mins) was so unnecessarily done, like what?? And not to mention the explanation of the swapping just being said on a passing with no further elaboration. And the ark of the FL's doctor friend finding out about the swapping just built to lead to nothing. I was half expecting him to go full on villain 😂😂. Anyway just like many other c dramas this drama do become draggy during the middle portion. But is somewhat tolaratable. The pacing picks up too.
