Wide shot of a mist-shrouded abandoned clearing in the sea of clouds; A curious girl named 小屿 runs forward, her gaze fixed on a quiet girl named 绫音 who is crouching by an old rusted metal crate. Soft twilight and swirling fog set the mysterious atmosphere.
Medium shot; 小屿 extends her hand toward the metal crate's protruding bolts, while 绫音 quickly stops her with a gentle but firm gesture, her expression calm yet cautious. The old crate stands between them, half-buried in mist. 别碰。
Close-up shot of the metal crate's front name plate; 小屿 and 绫音 lean in closely, their faces near the engraved tags on the plate. Faint mist reflects on the cold metal surface, making the faint engravings visible. 看，铭牌上是我们的名字缩写……
Low-angle shot looking up; The metal crate's lid flings open violently with a loud clank, a half-rusted train head emerging from the sea of clouds. The train's bright headlights shine directly at the two girls, making them blink and recoil.
Over-the-shoulder shot from 绫音's perspective; 绫音 grabs 小屿's arm and pulls her into the shadow of the train head. In the foreground, 小屿's fingers are slightly transparent as she looks down at them in confusion. 快躲！
Extreme close-up of the crate's glowing name plate; The plate emits faint blue light, and the word 'COUNTDOWN' appears slowly. 绫音 leans in, her lips moving silently as she murmurs an unknown syllable, her eyes focused.
