It's really just the story of two assassins backstabbing each other.
Yang Yuan: Thank you for your arrow, you let me know that I can still study in Liyuan without becoming an assassin in the future. (On the improvement of acting skills and tone)
Zhou Shiyan: Thank you for your affirmation. It would be better if you could remove the knife of our love from my neck.
They don't seek each other's will, but they have the same aspirations.
Respect freedom.
Respect justice.
Intention: The origin of justice is the intersection of freedom and rule-based will.
