Koo’s obsession only grew stronger after that night. Every time she remembered Taehyung bringing another woman home, the jealousy twisted inside her like a knife. She couldn’t let it happen again. No, she needed to make him see her—really see her.

And so, she began plotting.

If Mimi thought Koo was slutty before, she had no idea what was coming. Koo started dressing even sluttier when she went over—tiny skirts that barely covered her pussy, thin tops that made her nipples visible, shorts that rode up so high she looked naked from behind. But more importantly, Koo started timing her visits.

She knew Mimi’s schedule. Knew when Mimi had classes, when she was out with friends, when she wouldn’t be home until late. And those were the days Koo would show up at the house, pretending she was just dropping by. But it wasn’t Mimi she wanted to see.

It was him.

One afternoon, Koo rang the bell knowing full well Mimi wasn’t there. Taehyung opened the door himself, frowning in surprise when he saw her standing there in the shortest red skirt he had ever seen and a white tank top with no bra.

“Koo?” His brows furrowed. “Mimi isn’t home right now.”

“I know,” Koo said sweetly, stepping past him as if she belonged there. The sway of her ass was deliberate. “I just… wanted to hang out. Maybe keep you company?”

Taehyung blinked, clearly caught off guard. “Keep me company?”

“Mmhm,” she purred, dropping her bag on the sofa and plopping down like it was her own house. She crossed her legs slowly, the hem of her skirt riding up until the soft pink of her panties peeked through. His eyes flicked down before he quickly looked away, clearing his throat.

“You shouldn’t… dress like that around me,” he muttered, moving toward the kitchen.

Koo smirked. “Like what?” she teased, her voice dripping with innuendo. “You mean like a good girl? Or like a bad one?”

He stopped in his tracks, his shoulders stiff. She could see the faint pink rising along his ears. Oh, he wasn’t immune. He was just trying to fight it.

“Don’t play games, Koo,” he said firmly, though his voice lacked the conviction he probably wanted it to have.

She leaned back on the sofa, arching her back so her tits pushed up against the thin fabric of her tank top. “I’m not playing games, Mr. Kim. I just like spending time with you. You’re… different from the boys Mimi and I talk about.” She let her lips curl into a sinful smile. “You’re a man.”

That word hung heavy in the air.

Taehyung inhaled sharply, then busied himself pouring a glass of water, ignoring her. But when he returned to the living room, Koo deliberately bent forward to grab her bag, her skirt hiking up so far her pussy lips peeked out from the sides of her thong.

The glass clinked against the table as Taehyung set it down too hard. “Koo,” he warned, his voice low.

She turned her head, pretending innocence, though her eyes gleamed with mischief. “What? I dropped something.” Her thighs spread just a little wider as she stayed bent, giving him a shameless view of her glistening pink slit.

He clenched his jaw, looking away quickly, but not before she caught the heat flickering in his gaze. Her heart raced with victory. He wanted her. She knew it now.

“Do you always look at me like that, Mr. Kim?” she asked softly, tilting her head as she stood up, stepping closer. “Like you’re trying not to think about what’s under my clothes?”

He exhaled sharply, rubbing a hand over his jaw. “Koo, you’re Mimi’s best friend. This is… inappropriate.”

She giggled, brushing past him deliberately, her tits grazing his arm. “Inappropriate doesn’t mean we don’t want it.”

For a moment, he froze, and Koo felt the tension buzzing in the air. She was so close she could smell the faint scent of his cologne, feel the heat radiating from his body. His broad chest rose and fell faster than before, and his eyes betrayed a flicker of something raw.

But then he stepped back, putting distance between them. “Go home, Koo,” he said, voice rough. “Before you do something you regret.”

Koo smiled slowly, licking her lips. She picked up her bag, not disappointed but thrilled. Because now she knew—Taehyung was cracking.

And she was going to break him.

As she walked out, she made sure to sway her hips extra wide, letting him burn the image of her dripping pink lips into his mind.

Soon, she promised herself. Soon, he won’t be able to resist me.
