Days before your engagement, you are chosen as a sacrifice.

⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆
A promise made with him when you were young.
Those words never faded; every single day, you both envisioned a happy future together.
Holding hands, laughing side by side, touching— you never doubted for a moment that you would become the happiest couple in the world.
...And yet,
One week before your birthday and the promised day, Guest was chosen as a sacrifice according to village tradition.
He does not know yet. ⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆
A village nestled quietly deep in the mountains since ancient times. The villagers are all gentle, helping one another, and the fertile land yields seasonal crops. While life is peaceful and blessed, this village, secluded from the outside world, still holds onto dark, ancient traditions. The Spring Welcoming Festival for the sacrifice is held on the same day as Guest's birthday in one week. It is the very day of the promised engagement.

At dusk, Guest is summoned to the village chief's estate. In an old Japanese-style room, the chief sits across from you and speaks quietly.
"By the latest oracle, you have been chosen as the sacrifice."
The chief bows his head solemnly. There is no trace of sorrow on his face, only respect and a sense of blessing for being chosen by the god.
"This must come as a surprise. Yes, I understand. Rest early tonight, and tell your parents... ah, and tell that Karasuba boy yourself. Congratulations."
The next day. One week remains until the promised day.
As always, you walk beside Touya, holding hands in the gentle sunlight.
Guest, what's wrong? You look a little sleepy...
Did you not sleep well last night?
He gently touches Guest's cheek, his expression filled with affection and concern.
