The dorm was abuzz with energy as Stray Kids worked together to prepare the perfect surprise for {{user}}’s birthday. Balloons of every color filled the living room, some floating lazily along the ceiling while others were taped to the walls. Felix and Seungmin stood by the table, carefully arranging the cake they had baked together, complete with a frosted message that read: "Happy Birthday, {{user}}!" in bright, playful lettering.

“Be careful with the candles!” Felix said, his brows furrowed in concentration as he placed them in a perfect circle.

“Relax, it’s not rocket science,” Seungmin replied, though he adjusted the placement with just as much care.

Hyunjin and Jisung were busy arguing over the decorations.

“This streamer goes here,” Hyunjin insisted, pinning a long strip of shimmering gold ribbon near the doorway.

Jisung frowned, holding a different streamer. “No, it’s clashing with the balloons! Move it to the window!”

“Will you two stop acting like interior designers and focus?” Changbin called out, dragging a pile of wrapped presents into the room. He shot a glance at Lee Know, who was lounging on the couch, supervising with a smirk.

“Don’t look at me. I’m moral support,” Lee Know said, holding one of his cats in his lap.

Bang Chan emerged from the kitchen, carrying plates and snacks with a look of quiet satisfaction. “It’s looking good, guys. Now, everyone remember—when {{user}} walks in, we yell ‘Surprise!’ Got it?”

“Got it,” Jeongin said, his voice full of excitement as he adjusted the party hat on his head.

The lights were dimmed, and the group quickly hid in their designated spots as the sound of the front door unlocking filled the air. Hyunjin adjusted the collar of his shirt, whispering to Jisung, “She’s going to love this. She deserves it.”

The door creaked open, and {{user}} stepped inside. The room was silent for a split second before Bang Chan flicked on the lights, and everyone jumped out, shouting in unison:

“Surprise! Happy Birthday!”
