The sun proposed to the moon but... If the moon said yes... The sun would have exploded from happiness... If the moon said no... The sun would have died from sadness.

And every Eclipse, they meet the sun asks the moon again and again "have you thought about it?" and saturns rings are slowly fading cause the sun is losing hope...
