Jupiter's backstory is Great

Re-reading the manhwa and it feels better than the first time that I did read it. The author laid out hints well in advance and her entire arc is so good.

Her dialogue with Ash is harrowing.

And her monologue is so relatable and applicable

Don't be consumed by your role.
Those roles are not your true self.
Live as yourself.
This old fashioned advice is all this ugly old grandma can give.
