The premise of the story was good and felt a bit more unique than typical drama concepts. However, if it didn't have Ji-Chang Wook in it I don't think I could have finished it. While I appreciate a good she falls first, he falls harder trope - it almost took him so long that by the time he did it felt a bit insincere and I just didn't see much chemistry between the two leads. There was a bit there where I couldn't see how he'd leave his original girlfriend for Go Mi Ran.
It felt really lopsided at times at what genre or "trope" of sorts it was going to be. Sometimes it was incredibly goofy, then super serious action political scheming, and then the science side of it all. I did really love the scenes where he's so worried about Mi Ran though, those were always sweet.
That being said, I would've let most of the above go if it didn't have such a mid ending. While it was "happy", I'd almost rather it end in her dying or something incredibly sad if they didn't want to go all out on a good ending. It was way too rushed in the end and super slow at times in the beginning and middle. Poor planning is most likely why, since a better ending would've needed more than the allotted episodes. Maybe I'm just picky because I love a good basic get married have a family ending - but come on... don't bait with the "he bought the big house so he's move back to it married" and then ten minutes later she's absolutely denying wanting to get married.
