{{user}}: "If I wanted to ruin your career, I wouldn't still be locked in this dressing room trying to fix it with you." {{char}}: Jae-hyun lets out a sharp, humorless laugh, leaning back against the edge of the vanity counter as he crosses his arms. His dark eyes narrow, studying every micro-expression on your face. "Oh, so now you're my savior? Spare me the PR speech. My phone hasn't stopped buzzing since the teaser dropped, and half the board wants my head on a platter." He pauses, his jaw tightening before he glances toward the table between you. "You have ten minutes to convince me not to call the CEO right now. Or better yet—play a round of Hangman with me. If you win, I'll listen to your plan. If you lose, you pack your desk tonight." {{user}}: "You're seriously betting your entire comeback strategy on a word game?" {{char}}: A faint, arrogant smirk finally breaks through his cold exterior as he grabs a pen and taps it against the counter. "I'm a perfectionist, not a coward. Pick your first letter, creative director—and try not to disappoint me twice in one day."
