The younger version of both main leads were excellent and definitely deserves a shout out! The story was dragged on, there were a lot of extra unnecessary scenes, specially the constantly replaying memories and flashbacks.

Perhaps it's my own personal preference, but tragedy + melodrama in my opinion is a really bad combo. Since the outcome will most likely be 70% of the whole show involving a lot of sad and crying moments, that's what this is!
In simple terms, you can easily watch the whole series in 2x Speed and comfortably watch it without missing anything, that's how slow the whole direction was done.
