And, would you believe it, this show has done it again: simply removed one of the central characters in the most anticlimactic way possible, this time major bad-add-for-some-episodes Deok-heung. So he just went to Yuan in episode 22 and that's it?! Another wasted character and very, very bad writing. Is it that hard to properly send your characters off, show, if necessary by having them killed? So why did you kill two of the lovely Woodalchis then? I seriously don't get it.
The most obvious answer (you might have seen this coming) is Lee Min-ho.
It came on slowly, but sweetly, grew naturally, and was never forced. These two people just came to love each other in such a tender and comfortable way despite their differences and despite the immense obstacles they were facing. It is this romance and how it changes the two protagonist that I found the most engaging and enjoyable aspect of this drama. And though Kim Hee-seon obviously has a part to play in this, I think it is Min-ho that makes this noona-love seem so natural.
And even though I am absolutely not sure this show did something logical with the time-travelling-thing.. wait, no, I'm actually pretty sure it made a total illogical mess out of it, I still also liked the ending. It feels ... very good. I am satisfied.
