The grand mansion was no longer a fortress of silence and fear. Now, its halls echoed with the most beautiful sound in the world: laughter.

In the sun-drenched living room, littered with expensive toys that were far more fun to chew than to play with, a chaotic scene of pure joy was unfolding. A chubby little boy, no more than a year and a half old, was waddling as fast as his tiny legs could carry him, his giggles bubbling through the air. He was the absolute spitting image of his father, with the same dark, expressive eyes and a head of soft, dark hair. This was Kim Taegguk—their Ggukie.

Chasing after him was none other than the feared mafia leader, Kim Taehyung. But the man crawling on all fours on the plush carpet was not a boss. He was just "Dada." He let out a playful growl, and Ggukie shrieked with delight, collapsing into a giggling heap just as his father scooped him up.

"Got you!" Taehyung laughed, blowing a raspberry on his son's neck, making him squeal.

From her spot on the large, comfortable sofa, Koo watched them, her heart so full she thought it might burst. She was curled up under a soft blanket, a slight, familiar queasiness lingering from the morning. Her hand rested on her stomach, which had just begun to show a new, gentle curve.

"Look at him," she said, her voice warm with affection. "He already gets away with everything because of you."

Taehyung carried Ggukie over, plopping down next to her and settling their son on his lap. "Of course he does. He's a genius. He knows his Dada is wrapped around his little finger." He leaned over and kissed Koo, a slow, tender kiss that still made her toes curl.

Their peaceful moment was interrupted as Ggukie, deciding his mama was far more interesting, launched himself from his father's lap and into Koo's arms with a determined, "Mama!"

He immediately buried his face in her chest, his little hands patting her. "Booboo," he mumbled contentedly, declaring his favorite spot in the whole world.

Koo chuckled, adjusting him. "Yes, yes, your favorite pillows," she said, rolling her eyes at Taehyung, who was watching them with a look of such profound love it took her breath away.

"It's not my fault he has excellent taste," Taehyung said, his smirk back but now filled with nothing but adoration. His eyes then drifted down to her stomach. "Just like his father."

Koo groaned, playfully swatting his arm. "Don't you even start! This is all your fault," she grumbled, though there was no real anger in her voice, only a teasing warmth.

"My fault?" he feigned innocence, scooting closer and wrapping an arm around both her and their son. "I seem to recall you being a very willing participant, my love."

"Shut up," she muttered, blushing as she leaned her head on his shoulder. Ggukie, sensing the cuddle, snuggled deeper into her.

It was true. After Taehyung had dramatically reclaimed her from the police station two years ago, their life had been a whirlwind of healing, passionate arguments, and even more passionate reconciliations. The trust hadn't come back overnight. It had taken time, tears, and a lot of honest conversations. He had to forgive her betrayal. She had to learn to trust that his love was stronger than his pride.

And in the middle of it all, came Taegguk. Their miracle. Their living proof that love could bloom from the ashes of lies and heartbreak. The moment their son was placed in Taehyung's arms, any last remnants of doubt and anger had vanished, replaced by a fierce, protective love for their little family.

"So," Taehyung murmured, his lips against her hair. "A little sister this time, you think?"

Koo looked down at their son, then at her husband, her smile soft and complete. "As long as she has your eyes and my common sense, I don't care."

He laughed, a rich, happy sound that filled the room. Ggukie, copying his father, let out a happy gurgle.

In that moment, surrounded by the love of her life and their beautiful, naughty son, with a new life growing inside her, Koo knew. The dangerous game was over. The undercover cop and the mafia boss were gone. All that was left was a man, a woman, and the family they had built—a family that was messy, chaotic, loud, and perfectly, wonderfully happy.

They were home.
