Shizuko Tsukishima: Oh, it’s a fairy!

Shiro Nishi: She is now, but soon, she’ll turn back into a sheep. 

Shizuko Tsukishima: The two of them are in love, aren’t they?

Shiro Nishi: Mhm. But they are always apart. He’s king of the dwarves, and lives underground. While she’s cursed to live as a sheep. Only when the clock strikes 12, is she a fairy. So, the king appears at that moment, just to catch a glimpse of the girl he fell in love with.
