Mischief Managed (Stray Kids Oneshots)

Beach Day | Han Jisung

The sun was shining high in the sky, the sound of waves crashing against the shore filling the air. It was the perfect day for a trip to the beach—warm, breezy, and clear skies stretching as far as the eye could see. You stood at the water's edge, the cool foam licking at your ankles as you squinted up at Jisung, who was already bouncing around, full of energy as usual.

"Come on! Come on!" he called out to you, his voice full of excitement. He was already on his way to the dry sand, his flip-flops in one hand and a small plastic shovel in the other. "You're not gonna believe what I'm about to build!"

You raised an eyebrow, skeptical. "What, are you going to build a sandcastle?"

His grin only widened at the question. "Not just any sandcastle," he said dramatically. "I'm going to make the most epic, most impressive sandcastle ever."

You couldn't help but laugh. "Sure, Jisung. I'm sure it'll be the best thing ever." You turned back to the waves, your toes digging into the wet sand, but out of the corner of your eye, you saw him setting up a tiny fort with a determined look on his face.

It wasn't long before you walked back to where he was, unable to resist the curiosity of what he was actually doing. He was crouched down, intently patting the sand with his hands, occasionally glancing over at you with a little smirk as if daring you to be impressed.

"Here it is!" Jisung exclaimed, proudly standing up and motioning toward his creation. "The greatest sandcastle of all time!"

You blinked at the pile of sand in front of you. It wasn't really a castle—it was more of a lumpy sand mound with a few uneven walls sticking out of it like sad little towers. A few sticks had been pushed into the top, and there were some shells scattered around the base, which could've been charming if the overall structure wasn't so... well, questionable.

You bit back a smile, not wanting to hurt his feelings. "Wow, Jisung... that's definitely a sandcastle..."

He looked up at you, his face full of pride. "Right? I was going for a medieval vibe mixed with modern art. It's avant-garde."

You couldn't hold it in anymore. You burst out laughing, hands on your stomach. "Medieval vibe? Jisung, it looks like a sand blob with a couple of sticks stuck in it!"

He pouted, crossing his arms over his chest. "It's a masterpiece, okay? You just don't understand art."

"Oh, I understand art," you teased, bending down to inspect the "castle" more closely. "But I'm pretty sure modern art doesn't require this much... lopsidedness."

Jisung's pout deepened, but then, as if struck by a sudden burst of inspiration, he stood up straighter, looking at you with a mischievous glint in his eye. "Oh, yeah? Well, I'll just have to show you how impressive my skills really are. You ready for the next level?"

Before you could react, he grabbed a small plastic bucket, filled it with sand, and started dumping it on top of his creation with rapid precision. His hands moved quickly, patting the sand and shaping it with a focus that was almost... too serious. You watched, intrigued, as he sculpted a series of bumps and curves.

"What are you doing now?" you asked, leaning in.

He gave you a sly smile. "Wait for it."

After a few more minutes of intense "sculpting," Jisung stepped back and struck a dramatic pose. "Ta-da!" he announced, gesturing at his newest creation.

You blinked at the slightly taller pile of sand now in front of you. "...It's bigger?"

"Not just bigger," Jisung said, clearly proud. "It's got dimensions now. This is an architectural marvel, seriously."

You took a closer look at what he had built. It had a somewhat round top, a very questionable "moat" that didn't actually connect, and a few scattered shells. But now, there were a couple of poorly crafted stairs made from compacted sand leading up to the top. It was a big improvement, but you couldn't help but tease him again.

"Jisung..." you said, trying to keep a straight face. "It looks like a sand hill that's trying too hard to be a castle."

He gasped dramatically, placing a hand over his heart. "How could you! This is a grand structure!"

You could barely keep your laughter in. "It's cute, I'll give you that."

His eyes narrowed playfully. "Cute, huh?" he repeated, his voice lowering in a teasing way. "Alright, let's see how you do then. Show me your sandcastle skills."

You raised an eyebrow, not expecting that challenge. "Are you sure? I'm warning you, I might be better at this than you."

"Bring it on," he said, practically jumping in excitement.

You smirked. "Fine, but don't get upset when mine looks way cooler than yours."

You grabbed your own bucket, filling it with sand and packing it tightly as you began your own creation. You were determined to show him that, while his sandcastle was charming, there was room for improvement. The two of you worked side by side for a while—Jisung with his lopsided walls and exaggerated flourishes, you with your more precise sculpting and steady hands.

Finally, after much effort, you stepped back to admire your own work. It wasn't perfect by any means, but it was definitely a little more recognizable as a castle than Jisung's original creation.

Jisung turned toward you, looking at your sandcastle and then at his own, before dramatically clutching his chest. "I'm devastated."

You laughed. "Hey, I told you I was better."

He nodded sagely. "I'll admit defeat. Your sandcastle is, indeed, superior."

"And don't you forget it!" you said, hands on your hips, victorious.

Jisung smirked, eyes gleaming. "Okay, fine. But I'm still way better at making this fun."

Before you could respond, he flopped down in the sand next to your sandcastle and gave you a playful shove. "So, what do you say? Want to go for a swim and leave our masterpieces to be claimed by the tide?"

You grinned, dusting the sand off your hands. "You just want to avoid me demolishing your castle."

He shrugged, his grin widening. "Maybe. But hey, I'm fine with sharing the spotlight with you... for now."

Laughing, you both ran toward the waves, the sound of the ocean mixing with the joy of your playful day. And while Jisung might not have won in the sandcastle competition, he certainly won in the fun department.
