I was hooked only part way into the first episode. It's the highest rated drama on my list after my love from the stars. The only downside being one you already mentioned and that there is only one episode a week, which makes me very cranky. This and Liar Game are my new obsessions. I think in the future I will wait until a series is over to start watching it. It's not like there aren't plenty I can watch in the meantime...
I've fallen head-over-heels for this little drama. It's super funny and carefree, yet doesn't forget to give us little, as you said, "nuggets of wisdom" that can go beyond the situations of the characters in the show. My favorite characters are Min Do Hee and Lee Jae Hwan, the Whipped Cream couple, but I love pretty much everyone in the house for one reason or another. It's a little heartwarming, a little slice-of-life, and a bit of birth secret madness (that thankfully doesn't focus on that so much that it drags everything down) that warms my heart every week!
One of the best Kdramas I've watched. And it is quite impressive in it's genre as well. I think it's safe to say, even in comparison to English thriller shows, if not better, it is quite good.

Also, Jang Hyuk and Woo Bin, how can I not.
Also, thanks for writing an article on this show!
