first of all, i admit i only watch this drama because of changwook and bomin (& jinyoung though he only made cameo appearance, also because he promoted it on his ig)

I really can't relate to people who found this drama boring and calls it a disappointment, BLAME YOURSELF FOR HAVING SUCH HIGH EXPECTATION. Well, in my opinion i found this drama fun and at least way better than w3sk. The storyline is simple, nothing complicated and if you're finding typical grown-up sci-fi with love story drama, this might be suitable for you.
Also, one of the reason I probably enjoyed this drama because i liked how they add the sci-fi element.
There's something missing about this drama but i cannot point out what it is. Maybe because it doesn't have unexpected plot twist or any wow factor? Really, a simple drama.

I do skipped some unnecessary scenes but MOST IMPORTANTLY, at least the message in each episode reached to me. There were scenes that warmed my heart, a bit of slice of life too. People saying it's a rom-com but the comedy isn't really there, well you cannot expect watching a rom-com drama and laughs all the time, and with all honesty i did laugh a lot while watching this drama, it depends on individual. I really enjoyed it :)

The casts all did great in playing their characters, I liked the main casts chemistry with each other too though it's not the best i've seen but it is not awkward at all and that is enough for me. I have nothing much to say about the casts because i believe they've casted the best actors, my rating already said it all ;)

none of the osts catch my ears, maybe 2 or 3 but that is okay as long as we enjoyed the drama.
And for the rewatch value, though i said it is not a bad drama, i won't spend my time to watch this drama again. Again, just a good drama ;)
