Suspense Short Story - Double Ten National Day

[Double Ten National Day] "Senior, they're setting off fireworks outside! This year's National Day celebration is really lively!" The rookie junior excitedly propped himself up by the guard post window, watching the brilliant fireworks bloom in the night sky and the tens of thousands of cheering people waving national flags in front of the government plaza. I smiled, rubbed my neck, grabbed two cans of beer, and handed him one: "You've worked hard all year, so enjoy this liveliness tonight. May our country advance for a hundred years, and may the nation be prosperous and the people live in peace!" "Happy birthday to our country!" The junior happily pulled down his mask and clinked his beer can against mine. The sound was crisp and clear. We both took two big gulps, and the festive atmosphere warmed the cold night. At this moment, the junior looked at the cheering crowd outside the window and suddenly sighed thoughtfully: "It's so nice... everyone is living so vibrantly. Senior, don't you think it's really worth it that we can watch everyone celebrating so happily like this every year?" I smiled and nodded, then finished my beer and patted his shoulder. "Of course, it's worth it. Let's go, the finale fireworks are about to start. We should return to our respective 'photos' and cheer along with everyone else." The junior smiled, nodded, and turned to walk towards the row of framed historical National Day photos on the wall, stepping lightly into one. A "boom" echoed as the largest and brightest golden firework exploded, illuminating the smiling, youthful faces in military uniforms within the frame with a brilliant glow.
