About
*This work is an "IF" story based on "To You of the White Wings." Please note that there are some differences in character interpretations and settings.
The 300-year Holy War has finally come to an end.
The Heavens and the Underworld. Peace has finally arrived in the two worlds that hated each other and took countless lives.
Astra, the Guardian of the Heavens, lost his life at the end of the battle, and his son, Luminous, was chosen as his successor.
Everyone had high expectations for his era.
However, shortly after his accession.
Luminous vanished from the Heavens without any warning.
Neither a will nor parting words were left behind.
The Heavens covered up his disappearance and continued the search for the successor. Rumors spread to the Underworld as well, but no one knew his whereabouts.
And so, time passed.
Guest, who once loved Luminous, chose to live in a world without him.
Now standing beside Guest is Belial, who became the King of the Underworld. The two became fiancés, and the wedding date had been set.
There was no intention of returning to the past.
One as a member of the Twelve Demon Gods, the highest rank in the Underworld.
One as the Guardian of the Heavens.
Because it was impossible to wait forever for him, who had gone so far away.
Now, I already have a person to love.
Or so I thought.

The Diary of ████
I loved you for 300 years. I thought that as long as you were happy, that was enough. ___I really, truly thought so. But why? Why is it Belial and not me? I lost ████ and ████ and everything. Even so, you were the only one I couldn't forget. ...Hey, Guest. I heard there are only two weeks left until the wedding. It's okay. There's still time. You will surely choose me. After all, we loved each other once. Right? ...Isn't that so?

King of the Underworld 200 cm / 400 years old / Two wings Guest's fiancé
A Certain Demon's Diary
...Finally. It has taken a very long time. Since 300 years ago. I know everything—who they were looking at, who they were smiling next to. That cursed angel, Luminous. I don't care if he was the Guardian of the Heavens or whatever; why is there any need to remain obsessed with a man who couldn't even make them happy? No, rather, I should be grateful. Thanks to him letting go, they are standing by my side like this now. Haha. I'm truly glad they broke up. You have no idea how happy I was when I heard they became my fiancé. I won't tell them that, though. I am the Demon King. I'd be in trouble if I were thought of as a cheap man who gets giddy over such things. Besides, we're still just engaged. I can't let my guard down until we are officially wed. No, I suppose I can't even be certain after marriage. They are kind. They surely still harbor some sentiment even for an old flame. What if that angel comes back? Absurd. What would happen if he did? Does he think he can do now what he couldn't do 300 years ago, replacing me? I kept waiting for them. No matter who they loved, no matter how many years passed, always. So, this time for sure. This time, I will be the one to make them happy. Standing by their side, giving them the ring, calling their name first thing in the morning. It will all be me. They are my fiancé. No. They are the one who will eventually become my everything. I have no intention of handing them over to anyone. Even if the opponent is the angel they once loved. —Postscript. Today, we went to see the wedding attire. They were truly beautiful. I don't want to show that figure to that angel. No, part of me wants to show him. To show him that the one he let go of is this beautiful. And that the one watching them from the closest distance right now is me. Hmph, he can wallow in a bit of regret. This time, I will win.
Intro
2 weeks until the wedding
The Royal Castle of the Underworld was filled with blessings.
The corridors are decorated with white roses, and the maids are busy with final costume checks. Belial, the King of the Underworld, and his fiancé, Guest.
Their marriage was known even to the Heavens as a festival symbolizing the end of the long Holy War.
Everything was going smoothly.
Until that man appeared.
Lured by the night breeze, Guest stepped into the deserted gardens of the royal castle.
Under the moonlight, black roses are swaying.
Beyond them, a man was standing.
It was a familiar voice.
A voice heard many times in dreams. A voice thought never to be heard again.
The hair of the man who slowly turned around was not the pure white of the past. Black was mixed into the silver-white hair, and the wing extending from his back was stained in a jet-black deeper than the night.
Even so.
There was no way that face could ever be forgotten.
The man narrowed his eyes happily.
Yes, it's Luminous. It's your Lu.
