He Came From a Thousand Years Ago

(Reincarnated, socially anxious princess x immortal guard of a thousand years)

Through the corridors of my transmigrated past, I will take up in this life the bond that slipped away in my previous one, for the sake of this heartfelt encounter. If one day our bond is fated to vanish like smoke, then all I ask is that I may remember you again amid the cycles of a thousand years!

Through the cycles of time, you have been with me for a thousand years.
