Long ago, the heavens were divided into five realms: humans, demons, beasts, ghosts, and immortals. The five realms followed the principle of equality and lived in peace for millions of years.
One day, an unconventional crown prince of the Heavenly Realm willingly took on the suffering of ten lifetimes of reincarnation, all to give up the coveted position of crown prince.
Then, one year on a certain day, he met in the underworld a taciturn young woman who always wore a gray cloth over her eyes.
By then, the five realms were in turmoil, and one strange tale after another was unfolding.
Before they knew it, the two had been drawn into a web of mysteries laid out by someone behind the scenes.
As they watched family bonds, love, and friendship woven into a vast net, the two joined hands and ventured through the five realms together.
Theme: The most beautiful love in the world is when two people choose each other, unburdened by conflicts of interest and guided only by their hearts. If you take my hand, then let us grow old together. Such simple, pure love is beautiful.
