Love at First Bite

Kalyx, the golden dragon, loses a part of his sacred 'core' in the middle of metamorphosis. Celia was the one who took a bite out of it, mistaking it for a fruit. Kalyx vows to kill her in the next decade, but ends up meeting her as his maid. What could have been a dangerous cat and mouse game with Kalyx not recognizing a grown-up Celia slowly changes as the two gradually develop feelings for each other.
