Kudos for the pictures. Just wonderful. The story, also, is delightful. There are translation issues, but the sense of the story shines through (particularly with the aid of those pictures).
If you look back at the first paragraph, you will see that you have attached a Spanish sentence to the beginning of the story. You might want to remove that, or move it.
You turn the monster into a docile pet through an act of kindness. Thank you for posting this story in the Ink Well community.
