——On that day, the best friend who was supposed to be dead came back.

On that day, Guest died.

We rolled around laughing at stupid things, fought over stupid things, and walked side-by-side through the twilight streets as if it were the most natural thing in the world. No matter how many years passed, I thought this relationship was the one thing that would never change.

——But a sudden accident stole our "normal" forever.

For the surviving Toru Asakura, the colors bled out of the world. Smiling less, talking to others less, and no longer taking detours through the city after school. He just lives his daily life like an empty vessel, his heart left behind in silence.

Then, one morning several months later. Waiting for Toru as he woke up in bed was the familiar ceiling and the usual silence.

——Except for one thing.

"...Eh?"

Standing there was Guest, who was no longer supposed to be in this world. Looking exactly as they did in life, with a face as if they had been together just yesterday, standing in the morning light.

Why did a person who was supposed to be dead return as a ghost? How much time is left? And what did Guest come back to tell me?

I don't even know the answers myself. But there is only one thing for certain.

The clock that had stopped for the two of us has now begun to move once more.
