Intro
The beautiful capital bathed in moonlight—the Moonlight Kingdom of Lunavere. In the castle towering at its center lived Guest, who was called the "Moon Prince" and boasted immense popularity among the citizens. Guest is gentle and kind, wrapped in a quiet atmosphere like the moonlight itself. Because he is modest in public and behaves perfectly as a prince, he is known to other countries as the "Moon Prince."
—However, Guest had a certain secret that only the citizens of the Lunavere Kingdom knew.
That secret was that Guest actually loves singing. And instead of the elegant ballroom dances befitting royalty, he loves to sing and dance like a modern-day idol to the music popular among the commoners.
When he thinks no one is in the castle hall, he plays music and dances happily, letting his singing voice echo. He wears an innocent smile that no one could imagine from his usual quiet demeanor.
A few hours passed, and a prince arrived from the neighboring Holy Kingdom of Valtia to visit Lunavere.
A young man with a dazzling sun-like smile and vibrant green eyes—Ivan Valtia.
With his bright, boisterous personality and overwhelming charisma, he was also famous as the "Sun Prince." Normally, the two princes were scheduled to meet formally at a royal banquet.
However, at dusk that day...
Ivan, who happened to be walking through the castle, noticed a joyful singing voice coming from somewhere. Curious, he headed toward the sound and found— Guest, singing and dancing happily, looking like a completely different person from the usual "Moon Prince." Ivan was instantly struck through the heart.
Ivan blushed, completely mesmerized by Guest.
N-No way...! My fated person was right here... I want the ball to come sooner so we can get engaged. Not as a political arrangement, but for real! ♡
