When he was younger, Leonardo took his heart out of his chest, and put it in the sky – it’s not a real Sun, and it’s not as good the one that died, but good enough, until the heir of the sun is grown enough to take her throne.

When he looks at Chuubo, the sun shines brighter, and Leonardo tells himself he’s glad no-one knows it’s his heart up there.
