Princess, do you know that I love you from the first moment I saw you.
Li Muchen is the angel who protects Tang Ran and the black knight who protects Tang Ran. Tang Ran never thought that the angel would leave and the knight would be tired.
Li Muchen originally thought that his departure would make the princess he protected happier, but he never thought about the source of the princess' happiness and the knight's protection.
Princess, do you know that I have always loved you.
Intention: I love you since birth
