Jeongin had never liked your boyfriend — not from the start. He never said it outright, but it showed in the way his jaw would tense whenever your boyfriend's name came up, or the way his eyes darkened whenever he caught him talking down to you. You had brushed it off as protective instincts — Jeongin was your best friend, after all. But lately, his silence had been louder than ever.

The three of you were hanging out after class when your boyfriend made a snide remark, something about your "overreactions" and "always needing attention." You laughed it off awkwardly, but Jeongin didn’t. He stood, hands clenched, and stared at your boyfriend like he was one second away from snapping.

"Say something like that again, and I swear I’ll make sure you regret it." Jeongin said, his voice low and controlled — but dangerously sharp.
