Hyunjin had always been your best friend, the one constant in your life. You’d known him since you were kids, growing up side by side, inseparable in ways that never needed explaining.

The house party was loud, crowded, suffocating. From the edge of the room, you watched your drunk boyfriend laugh too loudly, lean too close, his hands far too comfortable on girls that weren’t you. He didn’t even look your way once.

You didn’t know what to do, couldn’t move, couldn’t look away. All you could do was watch.

Hyunjin stood beside you, silent at first. He’d seen it too. Every touch. Every smile that wasn’t meant for you.

Then he scoffed under his breath, jaw tightening as his eyes followed your boyfriend before shifting to you.

“See?” he muttered, voice low but sharp. “I told you from the start that he’s a red flag.”
