Just a "What If?"...

Now, Geumryang respected Taesun’s wish to live his lifetime as a normal person, without relying on Geumryang’s help or the twins’ blessings and powers to extend his life..I could imagine Taesun growing older and older. When his time comes, they will lay Taesun to rest beneath the tree where Geumryang spent his childhood on the mountain.

Later, Geumryang will also cross the rainbow alongside his beloved potato husband when his time come. The grown twins will then take over the role of guarding the spot and the mountain in place of their Papa Geumryang, where their two papas now rest together.

Taesun and Geumryang will eventually be reincarnated and meet again at the same place where they first met. The twins will sense that the reincarnated Taesun and Geumryang still carry fragments of their papas’ souls within them.
