i think this is one of the best kdramas ever.
the story, as you can see from the plot, is quite heavy so it may not be for everyone. i think the story itself unfolds really well in every episode. there are some things you can guess about, of course, but every episode has at least one plot twist. every evidence, quote, and scene has a meaning here. there weren't any necessary things that made the series longer. the cast is seriously good, they were fully immersed in their roles. especially as someone who loves children a lot, i felt terrible. all of it was so heartbreaking, and it gets even sadder when you remember that these kinds of things happen every day. i was quite surprised to see this drama isn't very popular, because it should reach more people. ost was quite good as well.
some scenes will haunt me for a while. definitely will rewatch, you should watch it too
