This show has so much great dialogue, so I wanted to add some that stuck with me. 

• Emperor of North Ji: "I won't lose a kingdom because of a romance!"
  Duan Zi Ang: "I don't care about the kingdom! I just want one person!" (Ep 9)
  
  
• Duan Zi Ang: "You'll die when I tell you to. You'll live when I tell you to. Even if the king of hell comes, he won't dare take your life!" (Ep 9)
  
  
• Duan Zi Ang: "You love the one who hates you, and you hate the one who loves you!"
  Xiao Shu He: "Aren't you both?" (Ep 9)
  
  
• Xiao Shu He: "I hate you, but I hate myself more. [...] What I hate the most... is that I love you." (Ep 12)
• Xiao Shu He: “I’ve made up my mind. If we are together, this imperial status will surely be an obstacle. If you are willing, I wish to wear these commoner’s clothes with you. Just like we promised. We will live in seclusion in the woods and roam the mountains and rivers together.”
  
  Zi Ang: “Of course I am willing. When the time comes, the two of us will find a courtyard in the woods and hold a simple wedding ceremony.” (Ep 8)
  
• Duan Zi Ang: "This heart is real." (ep 8)
  
  
• [...] "Can you feel it? From now on every beat here belongs only to you. Every beat will call your name." (Ep 8)
  
  
• Xiao Shu He: "Heart? But my heart was once right here." (Ep 10)
  
  
• Xiao Shu He: "Having you by my side is the greatest danger to me. The tighter I hold, the deeper the wound." (Ep 6)
  
  
• Duan Zi Ang: "Your tears hurt me worse than any blade." (Ep 12)
  
  
• Xiao Shu He: "I'm the fallen king, burdened with a hatred that can't be forgiven. However, if I weren't Xiao Shu He ... Let's do it again, Duan Zi Ang. Let's start over. " (Ep 12)
  
  
• Shen Song: "Must it come at the cost of your life?"
  Xiao Shu He: "I'll use what he treasures the most to take revenge on him. I'll use his suffering to atone to my father, my brother, my love, and to the people of South Hui Kingdom. " (Ep 12)
