The narrative flowed seamlessly from the opulent wedding to what should have been a private, intimate beginning. But with Selena, Soo-jin implied, nothing was ever truly private.

"For their honeymoon, they went to Jeju Island," Soo-jin continued, her tone laced with a knowing cynicism. "Picture perfect, of course. And yes, they passionately loved each other." She said the words without blush, a simple statement of what was expected, though the slight tightening around her eyes suggested she believed even that passion was part of Selena's performance.

"Min-jun loved the sea," she explained. "He'd always dreamed of riding a cruise. So, they spent six days sailing, the blue ocean all around them." A faint, genuine smile, the first, touched her lips as she recalled her brother's lifelong dream. But it quickly vanished.

"And what did Selena do?" Soo-jin's voice grew sharper. "She made videos. Endless, glossy, perfectly curated videos for her Instagram. Smiling, laughing, pointing at the sunset, tasting local delicacies—all while talking about 'love' and 'new beginnings.'"

She looked directly at Jae-hyun, willing him to see the calculation. "She wasn't just on her honeymoon, Detective. She was on a working trip. Every post, every story, every reel was content. She was building her brand, gaining thousands of new followers. Her popularity skyrocketed. And it all indirectly promoted her acting career, using my brother's dream vacation as her personal filming set."

Soo-jin leaned back, the picture complete. "He thought he was sharing a romantic adventure with the woman of his dreams. But he was just funding and starring in her latest promotional campaign. He was the handsome, faceless husband in the background, the accessory that completed the picture of her perfect life."
