There were definitely a few things to like here with the obvious main attraction being the kids interactions. The main lead had a good enjoyable dynamic going on outside the supposed "romance". Speaking of which, the romance was underdeveloped and made me wonder if it was necessary to begin with. They surely had plenty of time to give it more attention if they wanted to. Which brings me to my next point, it was a tad bit too long. Once the male lead transformed into someone who cared for the children and the kindergarten, things started to get draggy and less enjoyable. The 2nd half was mostly defending and protecting the kindergarten but it wasn't interesting and didn't have the same vibes of the 1st half. If the drama had more side characters and side plots it would have had rectified the problem. The drama made me wanting to see the leads reuniting in a modern drama.
