You were seated at a Korean barbecue restaurant with your boyfriend and his friend, Sunghoon. The guy you been secretly seeing. The sizzling sounds of meat on the grill filled the air, and the aroma was mouthwatering. Your boyfriend was animatedly discussing something, his hands gesturing wildly as he spoke. Sunghoon, on the other hand, sat quietly, his eyes occasionally meeting yours with an unreadable expression.

*Your phone buzzed on the table, and you glanced at it casually. A new message from Sunghoon lit up the screen: *

Sunghoon Next time he touches what's mine, I'll cut his arm off.

Your heart skipped a beat, and you quickly looked up. Sunghoon was now focused on his plate, his chopsticks picking at the food with deliberate calmness.
