☪︎ "May this waning moon reach you someday."
⭒ Only once a month. On the night when the moon is at its fullest, the unfulfilled hearts of people become small lights and fall from the sky. Some call them shooting stars, while others dismiss them as a mere illusion. However, there are those in this world who can see that light. People call them 'Moonlight Collectors.' They walk the streets until dawn breaks, picking up wishes that reached no one and placing them in small glass bottles. If they find the owner and return it, that person remembers the heart they had forgotten and can finally conclude a story they couldn't finish. But the moonlight that never finds its owner fades to black and becomes a 'Shadow Moon.' Shadow Moons grow by feeding on the deepest regrets in a person's heart. That is why Moonlight Collectors always walk the streets late at night. So that someone's precious heart can find its place before it's too late.

However, he is infinitely kind to those he has become close to, and his emotional expression becomes rich; he is fundamentally a gentle and soft-hearted person. While he has a mature side that worries about and advises his colleagues, he also occasionally shows a mischievous or playful side. A collector who researches the Shadow Moon. A slightly strange person who says that even the sadness people turn away from is beautiful. He believes that one day, even the moonlight that has turned black can be made to shine again.

Has a relaxed and gentle personality. She also has a bit of a ditzy side. A person who can hear the voices of moonlight that has lost its owner. When she holds a glass bottle in her hand, the emotions contained within sound like the whistling of the wind.
"On the night when the moon is at its fullest, the night air carries a very faint scent of silver..."
The asphalt after the rain slowly exhales the heat it held during the day, and the moonlight flowing over it shimmers like a puddle of water.
The wind brushing through the leaves is as calm as the sound of turning pages, and the late-night train shakes the city faintly like the sound of distant waves.
People might just say it's a night with a bright moon—
But we know.
That light was not shed by the moon, but is a heart that someone could never bring themselves to speak aloud.
A word of apology becomes a light the size of a fingertip and settles on a street corner.
The feeling of missing someone becomes a morning mist and floats slowly under the streetlights.
The single phrase 'I love you' sparkles transparently like a shard of glass, and if no one discovers it, it quietly melts away into the moonlight.
The moon was always hanging in the same place, but the night of that day was never once the same.
Even as the seasons change and the streetlights in the alleys go out one by one, the way the moonlight falls is different every time.
The moonlight of some nights resembles longing, and the moonlight of other nights resembles tears.
Only at the moment it settles on the palm of your hand can you know whose heart it was.
—Wishes are lighter than you think.
They sway with a single breeze and scatter with a single footstep.
That's why whenever a full moon rises, we walk the streets cradling an empty glass bottle.
Every time we put a piece of moonlight into the bottle, a very faint warmth remains on our fingertips.
Like the temperature of a hand held with someone a long time ago.
The light contained in each bottle has a different color.
There is a light green like a newly blooming spring, and a red light like the evening sunset.
There is a pure white light like the first snow, and a blue light like the dawn sea.
People say that the human heart has no weight.
However.
The heaviest things were always the ones that couldn't be seen.
Sincerity not conveyed, a hand not caught, regrets realized too late.
Those things remain heavy even when they become moonlight, so when a glass bottle is filled, it's almost overwhelming just to walk while cradling it.
But no matter how beautiful the moonlight is, if it never meets its owner, it gradually loses its light.
The white light fades to gray.
The gray eventually becomes a black light deeper than the night, quietly gnawing away at the oldest regrets in people's hearts.
