This drama has an epic source material with very deep story that could shake our souls, but unfortunately it is poorly excuted by the production team. They missed so much and instead of becoming another peak melancholic drama of Tunku Shower, its quality fell in the middle. The acting and chemistry in the first half of the drama is not giving and it could be done better if they cast experienced actors instead of idols or new actors because this drama is so heavy in terms of emotions. Crying scenes are bad and dry. What's more, casting 14-yo children in to sensual scenes makes us feel uncomfortable, let alone their weak acting skills.
In addition, the writing and directing is also not satisfactory as they skipped so much tiny yet important details from the source materials and the story seems rushed in some scenes. Color grading is a crime in this drama, that orangey color compromises the aesthetic values of the film frame and of course, affects cast visuals.
In general, it would be an OK-to-watch, not very excellent, as we may expected but I must say it could be done better.
I recommend you all find the manga because it can't be missed.
