The aloof prince and the forbearing piano player, one is domineering and the other is crazy. The two protagonists went from being suspicious of each other to working together to break the situation. In the game of established destiny and free will, they achieve self-salvation through emotional resonance. On the surface, it's a plotting conflict between the princes of the two countries, but on the inside, it's about two souls trapped in a prison of identity rescuing each other.
Purpose: In the cage woven by power and conspiracy, only with sincerity as the blade can we break the double shackles of blood and identity.
