Despite being an orphan, Layla Llywellyn feels lucky to live with her uncle Bill, a gardener on the picturesque Arvis estate in the Berg Empire.

To Layla, Arvis seems like paradise, she loves to explore the vast forest, always bringing her notebook to record the wildlife she encounters. She especially loves the birds, watching them with awe as they hatch and grow from fluffy chicks into beautiful birds. Duke Herhardt, the young, handsome lord of Arvis, is also interested in birds-and in Layla.

But the difference is, he’s interested in birds because he likes to hunt them… and he’s interested in Layla because he likes to make her cry. If a lovely bird is trapped in a golden cage, what will she choose: a life of luxury, or freedom?
