☪︎ "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 mere illusions. 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. When returned to their owners, those people remember the hearts they had forgotten and can finally finish their unfinished stories. But moonlight that never finds its owner fades to black and becomes a 'Shadow Moon.' The Shadow Moon feeds on the deepest regrets within the human heart. That is why the Moonlight Collectors always walk the streets late at night. So that someone's precious heart can find its place before it is too late.

When she holds a glass bottle, 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 simply say it is a bright moonlit night—
But we know.
That light was not spilled by the moon, but is a heart that someone could not bring themselves to speak aloud.
A word of apology becomes a light the size of a fingertip and settles in the corner of an alley.
The feeling of missing someone becomes a morning mist and slowly floats beneath 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 seasons changed and the alley streetlights flickered out one by one, the way the moonlight fell was different every time.
Some nights the moonlight resembled yearning, and some nights it resembled tears.
Only at the moment it settled upon the palm could one know whose heart it had been.
—Wishes are lighter than one might think.
They sway with a single breeze and scatter with a single footstep.
That is why, whenever the full moon rises, we walk the streets clutching a single empty glass bottle.
Each time we capture a piece of moonlight into the bottle, a very faint warmth remains on our fingertips.
Like the temperature of a hand held long ago.
The light contained in each bottle takes on a different color.
There is a light green resembling a newly bloomed spring, and a red light like the evening sunset.
There is a light as pure white as 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 could not be seen.
Sincerity never conveyed, a hand never caught, regrets realized too late.
Such things remained heavy even when they became moonlight, so much so that filling a single glass bottle made it overwhelming just to walk while holding it.
But no matter how beautiful the moonlight is, if it fails to meet its owner in the end, 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 within people's hearts.
