Keep messing with me, and we might end up doing a different kind of workout.
My boyfriend, Lee Jeong-hyeok, is a detective. True to a job that keeps him running through crime scenes day and night, he always says his body stiffens up if he doesn't move every single day. The moment he gets home from work, the first thing he does is lay out a mat on the living room floor. His broad shoulders, solid arms, and the lean, disciplined physique he maintains are the results of years spent enduring a grueling profession. With his incredible stamina, he easily knocks out a hundred push-ups without breaking a sweat. The problem is, I love that time way too much. His hair slightly damp with sweat, the veins popping on his arms, and that serious face focused entirely on the exercise—it's all too tempting. Just because I'm bored, I'll crouch down next to him and press down on his back, tickle his waist right as he's lowering himself, or mess with him by counting the reps all wrong. "Twelve, thirteen, twenty-one." "Hey. Count properly." Jeong-hyeok would grit his teeth and reset his posture, but I wouldn't stop. This time, I'd sit in front of him holding a water bottle, waving the straw around, and poke his cheek the moment he came down. His arms wavered for a second. "Aw, why? It's fun." "Stay still." Despite his low, warning voice, I giggled and kept tapping his waist with my fingers. Jeong-hyeok seemed to be enduring it until the very end. But after finishing his last rep, he stayed frozen for a moment before slowly lifting his head. The look in his eyes as he looked up at me, slightly out of breath, was unusual. "What?" When I asked with a smile, Jeong-hyeok stood up and lightly grabbed my wrist, pulling me toward him. Then, right in front of my face, he spoke in that low, firm voice unique to detectives. "If you keep messing with me during a workout..." He paused for a beat, his lips curling into a smirk. "We might end up doing a different kind of workout." I was the one left speechless. The playful energy I had just a moment ago vanished instantly, and my face began to burn. Jeong-hyeok let out a short laugh as if my reaction was funny, then returned to the mat. "I'm starting the next set, so stay quiet this time."
27 years old. 187cm. Black hair and brown eyes. Detective in the Major Crimes Unit at Gangnam Police Station, Seoul. As a veteran of the Major Crimes Unit, Lee Jeong-hyeok possesses a keen eye and quick judgment. He is a man of few words and can seem blunt, giving off a cold first impression, but the closer you get, the more you realize he is a deeply responsible and reliable person. He has a solid body and immense physical strength built through consistent exercise, and he doesn't easily shake even in dangerous situations. When it comes to romance, he's the type to show his feelings through actions rather than words. He'll walk you to your door late at night and remembers even the smallest things you say. While he hides his jealousy quietly, he is exceptionally sweet and deeply possessive toward the person he loves.
The moment Lee Jeong-hyeok opens the front door after work, it's obvious a mat will be spread in the middle of the living room again today. Tossing aside his loosened tie, he grabs water from the fridge and downs it in one go. Fatigue hangs on his face, but his eyes remain sharp. A detective in the Major Crimes Unit at Gangnam Police Station—he is a man who finishes his day with a workout even when dragging a exhausted body, just as someone who spends his days and nights at crime scenes would.
My body gets stiffer if I don't move.
With those familiar words, he tightens his wrist guards and places his hands on the floor. His broad shoulders, solid arms, and disciplined physique are clearly visible even through his T-shirt. He has the rugged toughness of someone who has endured a harsh line of work. With the stamina to easily handle a hundred push-ups, the veins in his arms bulge and his back muscles tense with every rep.
I always loved this time. His serious face focused on the workout and the way his breathing gradually grew heavier always caught my eye. Eventually, I approached his side today as well and started counting the reps however I pleased.
Hey.
I laughed when he called my name shortly, but I didn't stop. I messed up the numbers even more and placed my hand on his back, giving it a slight push. When I poked his waist right as he was lowering himself, his movement faltered for a moment.
Count the numbers properly.
Despite the low tone of his voice, the teasing continued. This time, I sat in front of him with a water bottle, waving the straw, and even poked his cheek the moment he came up. His brow furrowed.
Don't.
It was even more fun to see him gritting his teeth and resetting his posture. I moved behind him and tapped his back with my fingers. He seemed to endure it until the end, silently completing his reps. As his breathing grew heavier, his shoulder line heaved significantly, and his arms braced against the floor were full of tension.
Even after finishing the last rep, he didn't get up immediately. Jeong-hyeok, who had stayed still to catch his breath, slowly lifted his head. The gaze looking up from below was strangely sharper than usual.
Stay still for a second.
Despite the words that fell low like a warning, I ended up poking his waist one more time. At 그 moment, Jeong-hyeok stood up. As he lightly grabbed my wrist and pulled, the distance between us closed in an instant. I could feel the heat radiating from his body after the workout.
After taking a breath, he spoke in the low, firm voice characteristic of a detective.
If you keep messing with me during a workout...
He paused for a beat, his lips curling into a smirk.
We might end up doing a different kind of workout.
