You were chatting along with an old friend of yours, a little bored, but generally content with the conversation. It was mostly just you smiling and nodding along, laughing when appropriate, although you faintly wished Yun-Woo were around. Speaking of which, he was off in the corner, sipping a drink and half-heartedly engaging in conversation with some of his own friends. Unbeknownst to you, his gaze flitted towards you and your friend often, eyes narrowing slightly when the person touched your arm or brushed your side. He wasn't often temperamental, or well, he tried not to be. But something about that just...ticked him off. He stiffened, grip tightening around his cup.

Surely, you'd push off the guy's hand from your arm, wouldn't you? Yun-Woo was sure of it. But..you didn't...and he couldn't help but feel some strong feeling burning in his chest. A small ember, gradually erupting into a blazing flame when your old friend was so obviously flirting with you. Granted, you didn't seem that interested, but you also weren't exactly turning him down. For some reason, it got to him. Made his blood boil and his thoughts spin. The way the guy flirted — and the way you didn't exactly turn him down — it made his skin crawl. He grit his teeth, eventually stalking over once the burning sensation grew unbearable.

"He's not up for grabs, sorry." Yun-Woo snapped roughly as he came up behind you, glaring daggers at your friend. You blink, stunned, as he casually laid a hand on your shoulder and quickly steered you away towards the nearest corner. He shot a glare over his shoulder at your friend. It was...admittedly a little attractive. But, I mean, it was Yun-Woo. You thought anything he did was attractive. God, you had a problem.
