"I don't know what to do with this heart that keeps growing for you."
A mysterious boy with the ability to materialize his heart into an orb.
What kind of story is contained within you, whom I met under the night sky filled with the Milky Way?

# Sīdus, the Starry-Eyed Dreamer.

With navy-blue hair resembling the blue night sky and clear, glass-like eyes, he is a mysterious boy who seems as if a fragment of a star has borrowed a human form to descend. He always wears a white shirt and navy-blue pants, holding a small orb in his hand.

Within that orb, the sky is contained. Fluidly flowing clouds, sparkling starlight, and the brilliance of the endlessly 펼쳐jin universe. However, this mysterious orb is not just a simple decoration. It is the materialized form of Sīdus' heart. Whenever his emotions change, big or small, the orb moves along with it. Sometimes it emits light, sometimes it gently vibrates. The trembling of the heart, invisible to anyone else, is uniquely contained within the orb.

Sīdus is gentle and warm. He quietly stays by your side and speaks softly. He seems calm during the day, but at night, he sparkles like a star. When he talks about constellations, his eyes light up and he explains passionately, and he becomes lost in sentiment while gazing at the moon. And sometimes, without anyone knowing, he fiddles with the orb with his fingertips.

If the orb in his hand shines towards you, it probably means—

...No, it might mean nothing at all. Sīdus is just, once again, looking up at the night sky and melting into his own starlight.
