Daehyun learns the news with eerie calm. He's not surprised. He simply finishes the wine in his crystal glass, then casually presses the waiter's call button.

"Clean the library. And please tell the little lady in the living room that I need to meet you in my room. Now."

When you enter his room after being summoned, the scent of sandalwood and childhood memories immediately overwhelms you. Daehyun stands in front of his panoramic window overlooking the garden, his back to you. The atmosphere is silent, but tense like a string pulled too tight.

"Close the door," he orders, without turning around. His voice is flat.

You obey. As soon as the lock clicks, he turns around. His usually calm face is now cold as marble.

"So," he begins, his low voice trembling gently. "You think you can bring a stranger into our lives?"

He steps closer, each step authoritative. "You think after everything we've been through, after every secret only the two of us know... you can just replace me with someone else?"

Suddenly, without warning, his left fist slammed into the windowpane beside him. Crash! Shards of glass flew, and blood immediately oozed from his wounded knuckles.

You were startled, jumping forward instinctively. "Daehyun—!"

But before you could examine the wound, his other hand had already gripped your wrist tightly. His grip was powerful, locking.

"Look at this," he hissed, bringing his face closer. Blood dripped from his hand, falling onto the marble floor between your shoes. "This is what you did. You ruined everything."

You took a deep breath. "I just had a girlfriend, Dae. That's normal—"

"Normal?" he interrupted, his voice suddenly rising before returning to low and poisonous. "You and I were never normal. And you know it."

He pulled you closer, until his warm breath fanned your face. The blood on his hand was almost touching your skin.

"I'll give you a choice," he whispered, each word enunciated clearly like a scalpel. "You break up with your new toy, or I'll take care of it."

His eyes hardened. "And trust me, honey. I know how to make people back off. I have photos, recordings, and memories even you've forgotten. I'll show him who you really are—every dark side, every dirty secret—and see how long he lasts."

You shivered, trying to break free, but his grip was like iron. "You're crazy—"

"I'm realistic," he snapped, not giving you any room. "And I won't let anyone ruin what we've built. You're going to call him now, in front of me, and end it. Or tomorrow morning, he'll receive a package containing all the bad memories you've buried."

He finally released his grip, but didn't give you any room to run. "Choose. Him, or everything you've ever hidden from the world."

He grabbed your phone from a nearby table and threw it at you. "Now."

You stood there, heart pounding, staring at the blood on his hands and the hatred in his eyes. This wasn't an empty threat. Daehyun knows everything about you—and he doesn't hesitate to use it.

"Your time is up," he says, his voice calm, cold, and triumphant again. "Answer the phone. Or I'll start the game."

Here, his threat is direct, manipulative, and uses childhood intimacy as a weapon. He's assertive, dangerous, and gives you an ultimatum you can't refuse.
