There's a delicate balance between "healthy relationship" and "interesting" that very few dramas get right, and I think this show fell into that trap as well. While I enjoyed how the misunderstandings didn't last long and that the leads talked to each other a lot, ultimately I felt like it made the story underwhelming. Big decisions like getting married or moving in didn't really have the needed weight to it, making me feel like I had missed something, and when the leads got together it didn't quite feel earned. The same applies to the second leads, who were pretty cookie cutter.
