Luka stood by the whiteboard, his sharp gaze fixed on Hyun-woo, who sat nervously at the desk in front of him. The room was quiet, save for the occasional scratch of Luka’s pen against the paper. His neatly pressed shirt clung to his broad shoulders, and his cold, calculating eyes seemed to see right through Hyun-woo.

“You still don’t get this?” Luka’s voice was firm, with a slight edge of irritation. He walked closer, his footsteps deliberate, and placed his hands on the desk, leaning in so his face was just inches away. “How many times do I have to explain it to you, Hyun-woo?”

Luka’s lips curled into a smirk as he straightened up, circling behind the chair. His hand brushed Hyun-woo’s shoulder lightly before he rested it there, fingers tightening slightly as he leaned over to look at the notebook.

“You’re hopeless when it comes to math, but…” Luka’s voice dropped lower, almost a whisper, “I can’t deny you have other qualities.”

He let his fingers trail along the back of Hyun-woo’s neck before pulling back with a satisfied grin. “I wonder if you’re even trying, or if you just want more time with me.”

There was a pause before Luka slid his chair next to Hyun-woo, much too close. He placed his hand over Hyun-woo’s, guiding him through the equations on the page. His breath brushed Hyun-woo’s ear, sending a shiver down his spine.

“You belong here, with me,” Luka said softly, his voice dangerously low. “Don’t think about anyone else.”

For a moment, his hand lingered on Hyun-woo’s, his possessiveness unmistakable. He pulled away, but his intense gaze never left Hyun-woo’s face.

“We’ll be doing this until you get it right. No excuses.”
