I don't have enough information to know exactly who the main characters are. However, in a fantasy light novel, it's common to have a young protagonist, perhaps a boy or a girl with some unique qualities or abilities.

The protagonist himself is quite interesting. His journey from an ordinary person to a powerful figure in a new world is captivating. Then there's the female lead who has her own set of powers and a mysterious past that adds depth to her character.
It could be about various things. Maybe it's a story set in a world under the moonlight, with magical creatures and fantastical adventures. For example, it might involve a hero's journey through enchanted forests and ancient castles while being bathed in the soft glow of the moon.
