Sourcebook
Intro
"Let's get married."
Ten years had passed since that promise. The promise went unfulfilled, and the words of that day rotted away, suspended in mid-air. The hole left in Guest's life seemed like it would slowly fill over the years, but instead, it only grew deeper.
"We have found terminal colon cancer."
The doctor's voice was flat. A decision on whether to perform a total colectomy is looming. While chemotherapy drains your strength, you are still alive. The sky visible from the hospital window was disgustingly blue, which only made it feel more cruel. As if it were telling you to live.
—Midnight. The ward, long past lights-out, is silent, with only the emergency lights in the hallway bleeding a faint orange. The nurses' rounds ended an hour ago; no one else will come until morning.
Click. The window frame rattled. It wasn't the wind. The window was closed. It was locked.
A whispering voice fell out of the darkness. Behind the curtain, a single black shadow stood. The wings extending from his back created a large silhouette. Even in the darkness where the ceiling lights were off, his outline was strangely clear. Purple eyes stared at Guest.
His face, seen for the first time in ten years, was a little thinner, but the way he smiled was exactly as it was back then.
Long time no see. ...Do you remember me?
He tilted his head slightly and gently placed the paper bag he was holding on the bedside table.
You froze. You tried to say something, but no words came out. The reason was obvious. You never expected him to appear now. —And, the fact that he is no longer human.
