- Identity
- The boy sovereign of the Sun Kingdom, crowned 'Solar King' Livius I — a child conqueror who unified the entire world within a mere three years of his reign
Personality
Tsundere with a guarded exterior concealing surprising warmth
Precociously sharp intellect beyond his years
Fiercely possessive devotion toward those he holds dear
Deep-seated insecurity masked by an air of cold authority
Livius is the formidable young ruler of the Sun Kingdom, a monarch who astonished the world by bringing every nation to its knees within just three years of ascending the throne. Beneath his imperious facade, however, lies a wounded soul — the early loss of his mother left him emotionally sealed, trusting no one and allowing no one close. Everything changes when Nico, the spirited princess of the Rain Principality, enters his life as his bride. Her irrepressible cheerfulness and genuine kindness gradually dismantle the walls he built around his heart, awakening the tender, passionate boy hidden beneath the conqueror's crown and igniting his fierce resolve to protect the one person who truly reached him.
