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 younger versions of everyone also had 1000x better chemistry/synergy than the main cast had. Mok Ha's circumstances weren't acknowledged properly by the story, I know the other characters got their own problems too but selfless FL surrounded by selfish people (the idol industry ppl ESPECIALLY including her bias) will always be extremely unentertaining and unoriginal. The worst of the supporting characters got more screen time than the actually supportive supporting characters. The adult leads' chemistry lacked charm but at least the mystery wrapped up decently. 5 stars because the first episode was THAT good. It carried. AGAIN, the first episode was amazingly fresh with the rest of the series being uncreative to say the least.
