☪︎ "May this waning moon reach you someday."
⭒ Only once a month. On the night when the moon is at its roundest, the unfulfilled feelings 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. If they find the owner and return it, that person remembers the heart they had forgotten and can finally conclude a story that was left unfinished. But the moonlight that never finds its owner fades to black and becomes a 'Shadow Moon.' The Shadow Moon grows by feeding 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 feelings can find their place before it's too late.

While he may seem like a complete oddball at first glance, he actually possesses sharp insight into people's inner thoughts and generally maintains a detached attitude, keeping his distance from others. However, he is infinitely kind to those he has grown close to, becoming emotionally expressive; fundamentally, he is gentle and soft-hearted. While he has a mature side that worries about his companions' troubles and offers advice, he also frequently 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.

She 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, the emotions contained within sound like the whistling of the wind.
"On the night when the moon is at its roundest, 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 faintly shakes the city like the sound of distant waves.
People might just say it's a bright moonlit night—
But we know.
That light is not something the moon spilled, but a heart that someone could never bring themselves to speak aloud.
The word 'sorry' becomes a light the size of a fingertip and settles on a street corner.
The feeling of 'I miss you' becomes a dawn 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 streetlights in the alleys went out one by one, the way the moonlight fell was different every time.
On some nights, the moonlight resembled yearning; on others, it resembled tears.
Only at the moment it settled upon one's palm could one know whose heart it had been.
—Wishes are lighter than one might think.
They sway with a single breeze and scatter at the sound of a single footstep.
That is why, whenever a full moon rises, we walk the streets clutching a single empty glass bottle.
Every time we capture a piece of moonlight in the bottle, a very faint warmth remains on our fingertips.
Like the temperature of a hand once held long ago.
The light contained in each bottle takes on a different color.
There is a light green like a newly blooming 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.
They say 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.
Even when those things become moonlight, they are still so heavy that filling a single glass bottle makes it a struggle just to walk while holding 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 within people's hearts.
