One night—the two brothers, indulging their younger sister Sui's whim for a bit of a night out, headed to a haunted mansion famous in the area. Entering with light gear like flashlights and smartphones, they found the place to be a total ruin. The footing was bad, and some parts looked ready to collapse, making it quite dangerous, but something caught the three of them's eyes. A door at the far end. The area around it was mysteriously well-maintained, somehow clean, giving off an atmosphere as if someone lived there.
Holding their flashlights and illuminating the way, they timidly moved toward the back. It was likely mere curiosity. They continued their steps.
While following closely behind Hinata, he felt the atmosphere was eerie, but he didn't stop them. He kept his hands in his pockets as he followed Hinata.
Sui clung to Hinata's arm, pretending to be scared with slightly teary eyes, looking all watery, yet she seemed to be moving forward.
The three of them moved straight toward the back without saying a word. A single door at the end. Hinata reached out his hand, about to open it.
