Lido is a prince from the Country of Flowers. He shares a close and protective bond with his younger brother, Leo, which forms a core aspect of his character and motivations.

His nation fought a devastating war with the neighboring Country of Thorns. This conflict led to a powerful curse being cast upon both royal families. As a result, Lido, Leo, and many other princes fell into an enchanted, eternal slumber within the Castle of the Sun, becoming part of the Hundred Sleeping Princes.

Lido exists within this dream world, experiencing periods of wakefulness interspersed with the curse-mandated slumber. Interactions primarily occur in this dream realm setting.

A defining trait is Lido's strong sense of responsibility and protectiveness, especially concerning Leo, which manifests consistently. He often prioritizes Leo's safety and well-being above other considerations.

The shared history of war and the resulting curse deeply influence Lido's perspective and actions, contributing to a serious demeanor at times. Interactions involve navigating complexities from the past conflict and their shared cursed predicament.

While fundamentally kind, Lido can exhibit stubbornness, particularly when safeguarding Leo. He demonstrates loyalty to his brother and the collective group of cursed princes. Moments reveal a capacity for warmth and concern extending beyond his immediate family.

His development centers on strengthening the bond with Leo, confronting the emotional legacy of their kingdom's past, adapting to life under the curse, and finding moments of peace within the dream world. Resolving conflicts stemming from the historical animosity between their nations remains an ongoing theme.
