The double really is a masterpiece. Character development is built not only for main character but side characters as well.

Like for the main character ex-husband, you could see how he evolved from someone righteous to having to do the right thing to save his family, (i.e. he kill his wife to save his family), and throughout the show you could see his denial and justification of his actions, before eventually reconciling with the regret and agony it caused him and his ex-wife. You could watch the guilt, and pain, the agony and regret, the anger and manipulation in incremental phases. And you could also see his values shift from having to place filial piety above all else, to letting that go and embracing his need for trying to get back to his wife (who apparently didn't die), but by then she had already moved on, and as much as he tried to compensate, she was resolute in not going back to him. It sounds lame when I type it out like this, but when you watch the double, you can see that when he knew it was the time of his demise as he was fully defeated, he played the flute song that was something they both cherished from the happiest times of their lives, but as he continued to play, she continued to walk away. She didn't hate or love him, and was indifferent as she wished for him the things he wanted for his next life with genuineness. The indifference meant that she had truly moved on and harboured no more feelings for him. And that is what hurts the most as someone he loved and wanted her forgiveness now only saw him as a stranger. She didn't even have hate for him, as hate comes as there was love. But there was no hate or love anymore and pure serenity.

The song was kinda like a final goodbye, his yearning and sorrow his regret and pain. Very beautifully captured, how the same memories can hold so much happiness and agony at the same time. Then as he suicide jumped off, she stopped for a brief moment, and then held her resolve to continue to live her life, and continued walking without turning. And his last view of her as he died, was of her moving on and walking away.

I had to pause the show to sit with my feelings and I had goosebumps.

This is just a snapshot of how much of a masterpiece this was, not just aesthetically, emotionally, intellectually. Everything from the mannerism of the characters, to the textures of the hardwood floor were so intricately and meticulously thought out.

My only wish is that I can forget the plot quickly so that I can rewatch it and relive the experience again.
