This week, it's the story of Stupid Ondal and the Princess Pyeonggang, where we see that it's Pyeonggang's birthday, and she can cry if she wants to. Oh, it's the next birthday, and she's still crying? Wait, three years down the road, and she hasn't stopped. Should someone find out what's wrong? The king just wants to threaten her with marriage to a guy he sees as terrible? Yeah, this should end well.
The creature is Lazy Laurence. He guards apple orchards. And also doesn't mind a little backwash.
