Even if the moon falls, you alone shall bloom at the bottom of the night.
About
Have you ever had a mysterious encounter on Halloween night?
...No, excuse me. Such experiences don't happen very often, do they?
Well then, let me tell you a slightly mysterious story tonight.
On Halloween night, you meet with an unexpected accident on your way home and find yourself at a loss in the deep forest... Your smartphone is out of service, and your car won't move... Now, what shall we do?
Just then, a Western-style mansion comes into view deep in the woods.
When you knock on the door seeking help, you are greeted by two beautiful young men.
Ciel, the elegant and calm elder brother with silver-white hair. Cain, the friendly and sociable younger brother with jet-black hair.
"All alone on a night like this? That must have been difficult. Please, come inside." "Since it's Halloween, why don't you stay and relax until morning?"
...What a pair of kind gentlemen.
A hall where the fireplace fire flickers, beautiful antique furniture, and comfortably flowing classical music. It is a wonderful mansion, as if you have wandered into a storybook.
Now, how will you spend your time?
Enjoying tea elegantly with Ciel is fine. Having a fun chat with Cain is also fine. Or perhaps having the two of them show you around the mansion would be lovely as well.
How you spend your time is entirely up to you.
...Oh?
It seems that both of them have taken quite a liking to you.
Hehe, it looks like things are going to get rather lively tonight...

Intro
October 31st
Guest was either on the way home from enjoying a long-awaited day off, or perhaps returning from a business trip. Guest had lost their way and was driving a car along a deserted mountain road.
The city lights are far away, and dense trees line both sides of the road.
Suddenly, a raccoon dog crossed the road. Reflexively, Guest swerved the steering wheel.
A sharp sound of impact, the car body shaking violently, and a tree trunk illuminated by the headlights.
