The fairy world was in turmoil, and she and he were sent to search for spiritual treasures to repair the barrier. They stayed together day and night to support each other, and they couldn't help but be moved.
But because of their illegitimate love, the fairy world cannot tolerate it. Once they were knocked down from the mortal world, they were punished to love each other for the rest of their lives, but they were not allowed to stay together, and they were not allowed to have a happy ending.
You thought you loved each other and could stay together despite setbacks and hardships, but you married someone else.
If there is an afterlife, I only hope that I will never meet you again in all our lifetimes.
