Once a year, the Sun and the Moon are allowed to meet.
No one remembers when the rule was made, only that it is older than language and stricter than gravity. The stars claim it was a compromise. The planets insist it was a kindness. The earth, far below, has learned not to ask why some beautiful things are brief. It only tilts its face upward and waits.
The Sun has always been first to feel the waiting. All year he burns in his place, burning with a discipline taken as indifference. He learns how to hold his hands open without reaching. He learns how to give warmth without asking for anything in return. Every dawn, he rises knowing exactly how far he is allowed to go. Every dusk, he sets with the knowledge that wanting has consequences.
The Moon prepares differently. She practices being whole. She gathers her scattered light and smooths the old fractures along her surface. Cracks left behind by past meetings, by centuries of almosts. Some of them never quite fade. She learns which ones can be hidden in shadow and which ones must be carried openly. She tells herself this is healing. When the day finally arrives, the sky changes its tone. The blue thins. The air tightens. Even the wind slows.
Neither of them moves away. When they meet, the world forgets itself.
Light bends inward. The day collapses into twilight. Birds fall silent mid-flight. Oceans pause between tides. For a brief, impossible moment, everything is held.
The Moon’s surface scorches where the Sun meets her. Heat etches through her careful wholeness, reopening seams she spent a year pretending were gone. Fine cracks spread across her like porcelain under pressure.
The Sun flares in answer, his light destabilizing. Loving her costs him pieces he cannot give. He dims, not from exhaustion, but from proximity. They do not pull apart.
Below them, people gather. They lift darkened glass to their eyes and murmur in awe. They see the shadow alignment but they do not see the scorch marks. They do not see the breaking. The eclipse cannot last.
Light begins to return. The Sun is pulled backward into himself, leaving warmth behind. The Moon drifts away, her borrowed brilliance already starting to fade.
As they separate, ash falls from the Sun, cooling before it ever reaches the ground. Small fragments break free from the Moon and burn up in the atmosphere, leaving no evidence they were ever part of her.
Neither of them looks at what is lost. They return to their places, forever changed and carefully radiant. The Sun rises again, warming the world with what he has sacrificed. The Moon shines at night with light that is not entirely her own, her cracks glowing faintly.
And the earth continues to spin. Obedient and unaware, warmed by what the Sun has given up and guided by light the Moon has stolen. The sky will remember the scorch marks. The Moon will remember the cracks. The Sun will remember the hurt. The world will remember none of it.
