If you love yourself some romance, found family and everyone's-troubles-are-connected (I don't know if that trope has a name or...) dramas, this show is for you.
I want to start this off saying that the undeniable stars of this drama are the leads, played by Kwak Dong-Yeon and Park Se-Wan. Those two have some of the best chemistry together and they were the reason I started watching this drama in the first place.
That being said, while they were the reason I started, they weren't the only reason why I kept watching. There are two families at the center of this drama's plot. The first isn't a biological family unit, but one of circumstance. Several different individuals wind up staying at the Nakwon Inn (or Paradise Inn as it's translated to) and develop a tight-knit family of their own. The second, the Na family. They're a chaebol family consisted of some (mostly) egocentric individuals, and Hae Jun (he's the only one that doesn't suck royally, in fact, he's pretty cool). Both families filled me with a different set of emotions. The found family was beautiful, the love and support that they provided for each other is enough to give you the warm fuzzies. I was particularly a huge fan of the brother-sister relationship between Woo Jae and Bak Ha. The chaebol family, as expected, pissed me off quite frequently. What I wasn't expecting was to find all of them (well, almost all of them) to have charming aspects to themselves. This doesn't typically happen when I watch a chaebol family in a drama, so it was quite refreshing.
Now, let's talk romance. The central romance was definitely my favorite, but all (but one, Woo Jae and Hae Ri are my ultimate NOTP) of the other romances were also interesting to watch. They had so much chemistry and it was fun to watch their relationships gradually develop. For sure one of my favorite parts.
One of the cool things about this drama is that all of the characters' stories are linked. In the beginning most of the central characters were at the area where the prime conflict (the death of Bak Ha's husband) took place. What's also interesting is that each member of the Nakwon Inn family has some sort of bone to pick with members of the Na family.
Last, and not least, we have the other star of this show, an adorable baby named Yeol Mu. Yeol Mu manages to make everyone love and take care of him. He has an incredible charm that will make your heart melt.

Overall, it's a great drama filled with family, love, and growth. If you're good with longer format shows, it's worth giving a shot.
