The first episode has a TON of rewatch value. It has such a different sensation from the rest of the drama that you'd think it was from another series. The child actors played their challenging roles extremely well with so much heart. In comparison, the rest of the drama has an unserious attitude coupled with a weighty plot making it unenjoyable and difficult to finish. The significant characters had zero charm but at least the mystery was wrapped up pretty well. 5 stars because the first episode carried.
