“A century ago, there was this young boy called Kim Myungsoo. His father was a well-known and rich scientist. And to top it all off, Myungsoo was also quite handsome and charming. Because of all those factors, every girl in town dreamed of marrying him. But he was nicknamed the boy without a heart, and for a reason. He liked to play with a different girl every week.

But one time, he crossed paths with Son Jieun, a girl similar to him in personality. Myungsoo played with her longer, making her think he'd truly fallen for her. Until he forgot about her three weeks later.

But Jieun was not normal. She was the daughter of a witch. As revenge, she stole his heart. Myungsoo’s father found out, and knew he had to do something before his only son died. He quickly rushed to the Valley of Fallen Stars, and saved a dying star. In exchange, the star would maintain Myungsoo alive and young for a century. And in that time, the boy would have to look for his heart so he could live normally.

Knowing that there was a possibility that his son would take longer to find his heart than what was left of the father to live, he created a moving castle. It was done with any material that he could find, so it was quite ugly from the outside. But from the inside, it was beautiful and majestic.

It is said that so far, Myungsoo hasn’t been able to find his heart, which is kept by the witch’s female descendants. All Myungsoo has in his favor is the fact that these descendants don’t know what he looks like, and that he can charm them into giving him back his heart,” you tell your class. 

To you, this is just a legend you chose to nominate as the school's festival's presentation. 

Never did you suspect you'd be helping it to find an ending.
