The lover of you, with whom they were living together.
The lover was an astronaut, often heading into the sky for work.

As usual, before setting off for space, he said with a smile,

“When I come back, there’s something I want to give you.”

That was their promise of marriage.

But he never returned.

Due to a spaceship accident, his beloved you truly became “a person above the Universe.”

Left behind on Earth, you found themselves alone in the room they had once shared, and began visiting his grave.

One day, a letter and a ring were placed before the tomb.

On it, just one simple sentence:

“When I came back, I intended to give this to you.”

From then on, every time you visited the grave, there would always be a letter waiting there.

The ordinary days they had spent together.
Trivial arguments.
The starry skies they had gazed at side by side.
The words “I love you” that they could never say.

It was as if the lover who had gone far beyond the heavens were still returning to you’s side.

Yet— he would never come back.

He, who had gone up to the sky for work, had indeed become a person forever beyond the clouds.

Even so, you continues to visit the grave today.

As long as there is a letter there.

And in the final letter, written with the words of a proposal that he had never been able to utter until the end, lay the truth.
