Princess Celestia may be an omnipotent demi-god who holds the sun in her hooves, but that doesn't mean she knows how to put her feelings into words any better than any other pony.

Luna, seeing this, wishes to help her, with the aid of a few friends...Even if one of those friends might have tried to take over Equestria a little while ago. Hey, Changelings do survive off of love, right?
