The memory of the tense family dinner faded, replaced by a more private, more telling scene that Soo-jin had pieced together from her brother's confessions. It was late at night, after the guests had left, in the very room where Min-jun would later be killed.

"Later that night, after the rest of us had gone home," Soo-jin narrated, "Selena was still riding the high of her announcement. Min-jun, ever the supportive husband, was asking her about the movie."

She painted the scene for the detective: Min-jun, eager and proud, and Selena, calm and calculating.

"So, this movie role," Min-jun said, his arm around her as they sat together. "Which movie is it? What's it about? Tell me everything."

Selena smiled, a slow, confident smile. "I've been talking with a director. A very visionary man. He wants me to act in his new movie. In the lead role."

"That's amazing! What's the movie called?"

"It's called 'Bellatrix'," she said, her voice dropping to a hypnotic, persuasive tone. "And I will be the lead. It's a powerful role, a woman who defies everyone to claim her own destiny."

Min-jun, the practical businessman, asked the logical question. "That's wonderful, darling. How much are they paying you? We should discuss the payment properly. You have to be careful, nowadays there are a lot of fake directors trying to scam newcomers."

Soo-jin paused, looking at Jae-hyun. "And then she delivered the blow."

Selena's smile didn't falter. "Oh, no one is paying me, Min-jun-ah," she said, as if it were the most natural thing in the world. "I will be paying. I am the producer of the movie. This is my dream, to bring this story to life. Can you give me some money for the movie? This is everything I've ever worked for."

In the quiet bedroom, Soo-jin let the statement hang in the air, mirroring the shock her brother must have felt.

"My brother was stunned," she said flatly. "He was a restaurateur. He understood cash flow, investment, return. What she was describing wasn't a role; it was a bottomless pit. She wasn't asking for his blessing on her career; she was asking him to fund a vanity project with his family's money, and she wouldn't even be paid for it."

It was the first time, Soo-jin implied, that the perfect porcelain facade of their relationship showed a deep, structural crack. The charming actress was gone, replaced by a ambitious producer, and her first demand was for him to open the family vault.
