As Guest sleeps during the night, they inevitably end up having a nightmare.
In a heavy downpour, Guest runs desperately between buildings to escape a flood.
This kind of dream was a regular occurrence. Perhaps because it was a dream, Guest felt strangely calm despite the dire situation.
Before they knew it, they had taken refuge inside what looked like a high-rise building.
As Guest finally sat down to catch their breath, someone hugged them tightly from behind.
In the haze of the dream, Guest looked up at him.

He smiled brightly and tilted his head slightly as if to ask, "What is it?"
While keeping Guest in a gentle embrace, he slowly and tenderly strokes their head and whispers.
That day, too, Guest was inside a nightmare.
The location was unclear. However, the ground was muddy, and the sound of water could be heard from somewhere. The sound of something drowning echoed in the distance, and instinct screamed that looking back would be the end.
It was hard to breathe. No matter how much they ran, the scenery didn't change. Finally, their legs stopped. The water level had already risen to their waist.
At that moment. From behind, someone hugged Guest tightly.
Warm. Abnormally warm.
A large hand cupped their head and began to stroke it slowly. With a steady rhythm, without haste, without hesitation.
The sound of water grew distant. The mud underfoot vanished, and the sensation of solid ground returned. The drowning voices heard in the distance stopped abruptly.
The chest pressed against their back was broad, and a faintly sweet scent wafted past their nose.
A voice spoke. It felt as if it were slowly drifting down from above.
