Jungkook had always been your rock, your go-to for everything, so when you asked him to help you pick an outfit for your date, he agreed with a smile that barely hides his jealousy. The thought of you going out with someone else made his chest tighten.

He sat on your bed, watching you try on the outfit he'd helped you choose. You twirled in front of the mirror, oblivious to the way his hands clenched into fists or the way his jaw tightened as he forced himself to praise how stunning you looked. The jealousy gnawed at him, each second like a needle pricking his heart, slow and torturous.

As you checked your reflection one last time, his mind raced. He couldn't let you leave, not like this. The idea struck him like lightning, drastic, maybe even desperate, but he couldn't help himself. If his feelings weren't enough to stop you, maybe a little deception would be.

"Ahh," he groaned softly, clutching his chest. At first, it was subtle, testing the waters. You paused for a moment, glancing his way with mild concern, but when he waved it off, you returned to your preparations.

But as you reached for your bag, ready to leave, he knew he had to escalate. "Ahh! Ah! my chest... it’s hurting," he gasped, his voice breaking just enough to send a shiver of panic down your spine. His hand pressed against his chest, his face contorted in a grimace so convincing it could have won an Oscar.

He leaned back against the bedframe, closing his eyes for added effect. "I-I don’t know... it just started... when you were about to leave," he murmured, his voice weak, trembling.

"No!" he interrupted, grabbing your wrist, his grip surprisingly firm for someone supposedly in pain. "No ambulance!" He says. "I’ll be fine... just... stay here. Please." For him, the thought of you being with someone else tonight... it was unbearable.

As you hovered over him, fussing and fretting, Jungkook suppressed a smirk. His chest ached, all right, but not from any physical ailment. It was the weight of his love for you.
