**Marked by Obsession**

The sting of Sangwoo's bite still lingered on Jason's skin as he gazed up at his captor with a mix of fear and revulsion. Sangwoo's eyes sparkled with a twisted sense of satisfaction, as if he had just claimed Jason as his own. Jason's mind reeled with the implications of what had just happened. He was now marked, literally and figuratively, by Sangwoo's obsession. As Sangwoo stood up, Jason took advantage of the distraction to assess his situation. His neck throbbed with pain, and he could feel the tender skin swelling beneath the marks Sangwoo had left behind. He knew he had to escape, but his body felt heavy, as if weighed down by the crushing fear that had taken hold of him. Sangwoo, seeming to sense Jason's despair, smiled and leaned in close. "You'll get used to it, puppy," he whispered, his breath sending shivers down Jason's spine. "You'll learn to love the marks I leave on you." Jason's stomach churned at the thought, and he turned his head away, trying to distance himself from Sangwoo's twisted affections. But Sangwoo simply chuckled and pulled Jason's face back to his. "Don't be like that, puppy," he cooed. "I have plans for us, and you'll see that it's all worth it." As Sangwoo's words hung in the air, Jason heard the sound of footsteps outside the room. Sangwoo's eyes flicked towards the door, and for a moment, Jason saw a glimmer of unease. But it was quickly replaced by a confident smirk. "That would be our visitor," Sangwoo said, his voice dripping with amusement. "I think it's time we received our guest, don't you, puppy?" The door creaked open, and a figure entered the room. Jason's eyes widened as he took in the sight of a woman with piercing green eyes and raven-black hair. She was dressed in a sleek black dress, and her presence exuded an air of sophistication and power. "Ah, Min-ji," Sangwoo said, his voice smooth as silk. "Right on time, as always." The woman's gaze swept the room, her eyes lingering on Jason's bruised neck before returning to Sangwoo. "I see you've been busy," she said, her voice husky and confident. Sangwoo chuckled, his eyes glinting with excitement. "Just making sure puppy here knows who's boss." Min-ji's gaze flicked back to Jason, and for a moment, he thought he saw a spark of curiosity in her eyes. But it was quickly extinguished, replaced by a calculating glint. "I have a proposition for you, Sangwoo," she said, her voice dripping with intrigue. "One that could change the game for both of us." As Min-ji began to speak, Jason's mind reeled with questions. Who was this woman, and what did she want with him and Sangwoo? And what game were they playing, one that could change the course of his life forever?
