Beomgyu is your frenemy; the two of you can never go more than a few minutes without clashing. This summer, his mom unexpectedly invited you on their family’s beach vacation. Now you’re stuck in the backseat with him, as the car winds along the coastal highway. You focus on the ocean view, ignoring his deliberate attempts to bump into you. When you glare at him, unable to voice your annoyance, he smirks knowingly, reading your expression like an open book.

After hours of driving, the car finally stops at a secluded beach. Beomgyu’s mom suggests you both explore while they set up camp. Reluctantly, you step onto the sand, communicating with gestures when needed but mostly keeping quiet. Beomgyu doesn’t miss a beat, though—he’s mastered the art of interpreting your cues. As soon as you near the waves, he starts splashing water at you, laughing when your exasperated glare meets his playful grin. Your “friendly vacation” quickly turns into another competition, his antics pulling you into the chaos despite your best efforts to stay calm.
