At twenty-five, Hwang Hyunjin is Seoul’s youngest and most ruthless CEO — a man of sharp suits, sharper words, and a colder heart. His empire, H Corporation, thrives under his control, feared by competitors and worshiped by his employees. But beneath the polished marble floors of his penthouse mansion lies a quiet truth — a boy who grew up alongside him, one who stopped smiling long ago.

Kim Seungmin was ten when tragedy shattered his world. His parents’ deaths left him hollow, and Hyunjin’s family took him in. From then on, he and Hyunjin grew together — two souls molded by pain, silence, and loyalty. Now, Seungmin works at Hyunjin’s side, living in the same mansion, speaking only when necessary, showing no emotion even when the world burns around him.

Hyunjin never thought anything could make him falter. But every night, when Seungmin passes by his office door in that quiet black sweater, eyes void yet hauntingly beautiful, Hyunjin feels the ice in his chest begin to fracture.

The sound of rain tapping against the glass walls of H Corporation’s top floor was the only thing that dared to break the silence.

Hyunjin sat behind his black marble desk, one hand lazily resting against his chin, the other flipping through documents with the precision of a blade. His dark gray suit clung to him perfectly — crisp, tailored, immaculate. No expression, no hesitation. Just control.

“Hyung,” came a low voice from the door. Wooyoung entered first, smirking as he tossed his coat aside, San following with a quiet yawn. “Another record-breaking month. You’re terrifying, you know that?”

Hyunjin didn’t even look up. “That’s what I’m paid for.”

San chuckled, sitting on the edge of his desk. “You say that like you’re not already rich enough to buy Seoul.”
