Right off the bat I enjoy the casting of the main leads for Gwi Ju and Da Hae. I like how Jang Ki Yong is playing against his usual cool guy role, being a dorky regular Joe Gwi Ju who has the mushroom/coconut hair. Chun Woo Hee is effervescent as Da Hae who gives off this endearing charm where it's understandable how people are drawn to and trust her. I love how both of the actors ground even a silly funny reactions so that they aren't cringey, which includes the bickering which is usually a fast forward moment in other dramas. I love the scene where Da Hae goes off to con a fourth husband in order to shake of Gwi Ju. She shows off her full con mode, she's very effective but Gwi Ju doesn't have any jealousy or anger or is even phased. Which was a preview version of later when he finds out she faked her death in an attempt to save him. He was angry and confused, but he just embraces her as soon as he realizes why she did what she did. Their chemistry is so good! Of the extended cast, Kim Geum Soon is really impressive as Baek Il Hong, Da Hae's loan shark turned adopted mom. She's fantastic at keeping her motives ambiguous as to whether she's sincere or a plot, whether she loves Da Hae or she's a cold hearted crime boss who will collect on Da Hae's due.

The writing for the most part is really good. The writing for this show actually understands how to withhold and reveal information with impact. They play with the expectations of the powers really well from the evolution of Gwi Ju being able interact with past Da Hae, to her revealing to him things his future self did but the audience aren't sure if she's lying or not and she's able to use this in a actual lie as well, to her simultaneously interacting with both past and future him, and how he's saved. The flower scene is probably the most trippy time travel event of the whole series, because she didn't lie but he also didn't buy the flowers until his future self gave them to her. Ina's friend/bully doesn't even know that Ina has the power to read minds when she looks into people's eyes but was unknowingly able to use it to mentally bully Ina. Da Hae is able able to flip Man Huem's fatalist viewing of her negative dreams into a reinterpretation of the events into a positive outcome, building on what her fellow regular human father in law Man Seok has been doing to make the positive dreams come true. Man Seok seeming like she was tricking Il Hong about a vision about seeing the daughter she lost (the one that died while she was in prison) grown and alive but actually was about embracing Da Hae who faked her death hit me so hard in the heart.

The weakest part of the writing is Dong Hee's storyline and struggle with eating and body image. Dong Hee was used a comic relief character when she was heavyset and then suddenly she's just all serious when she's lost the weight again. The optics of that is really suspect to say the least. I could see there was the intention of wanting to convey the reasoning behind Dong Hee not being able to fly was not actually her physical weight, but the crushing mental insecurity and regret, but I don't think the story conveyed that as well as it can be. Then the other weak parts was the unnecessary teasing of the scumbag doctor by Da Hae and Grace that causes him to push her out the window and then him being the one to cause the foreseen school ire that forces Gwi Ju to time travel to the past feels forced. It's like they just transferred all of Dong Hee's cartoony nature into him just to move certain plots along.

The conclusion is lovely though. It turns out Da Hae and Gwi Ju definitely got frisky at least once at some point because they have a son at the end and it's so beautiful that her child is who brought Gwi Ju back to the safety of the future. I thought it was funny that they didn't show Ina's face in the future, only that she has long hair. Her actress was probably actually around 11 at the time playing a 13 year old while all the class mates were played by 14 or 15 year olds which makes her look as small as possible, so I understand how it would be hard to age her up. They should have cast an older kid so she could reunite with her dad too. Overall the drama was very enjoyable to watch and it's always great to see kdrama try to do something different and mostly succeeding.
