The Three Realms have been peaceful for five hundred years because of a promise. Finally, the Demon Lord set off.
"Your Majesty, your sweetheart has passed away."
"I'll wait for her."
Five hundred years later, the person he cared about wanted him to die...
"I once loved someone, but I didn't understand love at that time."
We made a promise under the blue moon, and now we are also separated under the blue moon...
Intention: No matter what, there are always people who love you thousands and thousands of times in this world
