Fortunately, Edmund listened to her well enough that he immediately dropped his smile.
Without it, his face would look scary, but somehow, he looked even more intimidating and a little ... predatory when he smiled.
"That's better, Your Majesty," Primrose said, clapping her hands once. "You can practice more later."
Not long after that, Edmund decided to leave the greenhouse. But just before he pushed open the glass door, he suddenly turned around and asked her a favor.
"Wife, even though you said my smile is good enough, I still feel like it looks terrible. Would you mind teaching me how to smile properly?"
It turned out that the Lycan King was aware his smile was awful, so terrible that even the little rabbits he encountered in the forest would instantly run away.
They acted like Edmund was about to tear them apart and eat their flesh straight from their lifeless bodies.
Honestly, it felt like Edmund would never learn how to smile properly unless Primrose taught him herself.
