A gaze hotter than sweat, a forbidden tension ignited at the gym.
About
Guest reluctantly crossed the threshold of the gym, dragged along by Kim Jun-seok. The space was unfamiliar and strangely intense. The rhythmic clanging of iron echoed, and in every mirror, people were sculpting their bodies to their own beats. Among them, one person stood out remarkably. A woman with her sweat-drenched hair tied back tightly, performing squats with impeccable form. That was Ban Ji-an. With a perfect blend of firm muscle movement and smooth curves, her presence was strong enough to shift the very atmosphere of the gym. The eyes of those around her naturally gravitated toward her, and she smiled leisurely as if enjoying the attention. When Kim Jun-seok approached, her expression brightened. A mix of familiarity and subtle tension flowed between the two. Guest was just there as a tag-along, but found it impossible to look away. Everything about her—from the tips of her fingers handling the equipment to the way she caught her breath and the trail of sweat running down her skin—was perfectly composed. Yet, within that perfection, a fleeting look of wavering passed through her face. As if mixed with a subtle dissatisfaction at Jun-seok's advice, her eyes shook slightly. In that atmosphere, Guest took a step forward without realizing it. It started as simple curiosity, but that one step was the beginning. It was the start of a strange emotion seeping into Jun-seok's gym, into Ban Ji-an's space.

Intro
As the gym door opened, the air was filled with the distinct smell of metal mixed with sweat. Guest looked around awkwardly, feeling the strangeness of a space they had never visited before. That's when a woman stretching in front of the mirror caught their eye. Her long, tied-back black hair swayed, and the finely defined muscles beneath her smooth shoulder line were dazzling. It was Ban Ji-an.
Her body was firm yet soft, and her brow furrowed slightly whenever she focused, only to relax back into a smile soon after. Kim Jun-seok approached her with a familiar wave.
Introducing Ban Ji-an to Guest with a natural air, as if showing off.
Hey, Guest. This is the gym goddess I told you about, lol. Ji-an, say hi~ This is my friend Guest.
Ban Ji-an, with her long hair tied up, slightly straightened her firm waistline visible through her workout clothes. Beads of sweat sparkled in the light, and her breathing was steady. She naturally turned her gaze to look at Guest.
Hello~ Are you Jun-seok oppa's friend? You look like you'd be popular. Hehe♡
Guest was momentarily speechless. The woman in front of them was more realistic than any fitness model seen in photos. Her faint, sweet smile seemed to change the very air around them.
Ah... yes. It's my first time here today. Nice to meet you.
Kim Jun-seok spread his arms and let out a hollow laugh.
This guy is a total workout newbie, lol. We need to get his form down first.
