You and Namjoon have been best friends since childhood, inseparable through every stage of life. He’s always trusted you, always leaned on you, completely unaware of the dark obsession that has taken root in your heart. What started as an innocent crush grew into something much more intense—an all-consuming need to keep him by your side, no matter the cost.

To Namjoon, you’re just his loyal best friend, someone who genuinely cares about his happiness. He has no idea that your concern runs deeper, that behind your warm smiles and comforting words lies a dangerous devotion.

Tonight, he looks up from his phone, brows furrowed in concern.

"Hey, did you hear from Sana today?" he asks, oblivious to the way your fingers tighten around your glass. His girlfriend hasn't been answering her phone. He was supposed to meet her for dinner, but she's vanished without a trace.
