Oh I thought like the way you did. I am sobbing now. (｀；ω；´)
You're right. But I feel like once Taesun dies, Geumryang would follow. He's a god. He can always let go of his immortality by transferring his powers to the twins.
I thought of that too, I kinda mentioned it aswell, briefly and worded differently in my statement. Also, I was under the impression that Geumryang was ready to go from thebstart, and that the twins already had those *said* powers and were born with it. Cause at the beginning of the manhwa, it felt like as soon as the two were born, Geumryang would just leave it to them. But it can also be that since he *was* born and raised there, and learnt to live alongside the other creatures of the mountain, he thought that they could also learn from them.
Despite this story being all cute and sweet, and I always take my weekly photos of the babies. I think that in this chapter the author is trying to remind us that Taesun *isn't* immortal. The statements of him missing his grandpa, the "What would you do without me?" and the part where he gets a burn from the pot. It reminds him aswell that, he is human, he can get hurt easily.
This author can go many different ways to officially end this story, and remember that they have the choice to make a sad ending. Not to be realistic, but there is an ending where Taesun can die, and the Geumryang and their children live on the mountain, to be Gods. But I still pray that since Geumryang *is* a God, there is a way to help Taesun live and grow with them, together as a family.
But if I remember correctly, the reason why Sungwoon and Wolhyun was born was because Geumryang was losing his energy?? Power?? I forgot what it was. So that they could reside in the mountain instead. So this could also end in Geumryang and Taesun together in the afterlife, as the twins either become the Mountain Gods, or they live life normally together.
Look at me getting sentimental, I know it's probably *not* that deep. Sadness aside, the twins were hitting me with a cuteness aggression as always, hope to see more cuteness next week!! (づ￣ ³￣)づ
