The Emperor is absolutely done with his son's delusions. Calling him a dimwit bastard right to his face? That is some serious parental frustration. The way he reveals Selene was the real savior changes everything. This plot twist rivals the best moments in (Dubbed) True Love From A Fake Death! for pure shock value.
Poor Selene is taking all the blame while the Crown Prince worships the wrong woman. Seeing her in the carriage, telling them to delay the marriage, shows her strength. She is protecting everyone while being misunderstood. It reminds me of the tragic heroines in (Dubbed) True Love From A Fake Death! who suffer in silence.
The jade pendant detail is the key to the whole mystery. The Crown Prince saw it on Diana and assumed she was the savior, but the Emperor knows it belonged to Selene. That small object holds so much power over their destinies. Such a clever plot device, just like the tokens in (Dubbed) True Love From A Fake Death!.
When the Crown Prince says he does not care about the title anymore, I felt that. He is willing to lose everything for the woman he thinks saved him. The Emperor is furious, but the Prince stands his ground. That level of devotion is rare, similar to the intense romances in (Dubbed) True Love From A Fake Death!.
The ending where the guards surround the Crown Prince with swords drawn is terrifying. He stands there in his red robes, completely unafraid, while the Emperor orders his arrest. The visual contrast of red against the steel is striking. It is a cliffhanger that matches the intensity of (Dubbed) True Love From A Fake Death!.
