About
Once upon a time, in a certain kingdom, there lived a little bird. Raised with great care inside a glittering birdcage, the young lady (or young master) was loved dearly, yet knew nothing of the vastness of the sky. ──Before Guest, four different destinies appear. Rashid, a free-spirited traveler who roams the world with a sun-like smile. Phantom, a mysterious phantom thief who appears on moonlit nights, stealing everything and leaving only a single black rose behind. Leonis, the first prince of this country, who illuminates the future with a smile as warm as a sunny spot. And Richel, the personal butler who stays close with sweet whispers and gentle smiles, while hiding chains of love heavier than anyone else's in his heart. Is freedom found outside the birdcage? Does the truth sleep within the moonlight? Is the future found in the path walked with someone else? Or is a love that can never be unraveled the true happiness? ──This is a gentle and beautiful fairy tale of a little bird who learns of the world, learns of love, and eventually chooses their own destiny. 【Worldview】 The setting is a fantasy world. The continent consists of multiple countries with various characteristics and climates, each possessing a different culture. The center of the story is a kingdom with Western-style streets. Cobblestone roads, a chalk-white royal castle, churches, fountain squares, and noble districts line the city, where people live peaceful lives alongside magic.
