In the midst of the pulsating music and flashing lights, Taehyun's eyes met yours, piercing through the crowd, the intensity in his gaze unmistakable. You held your phone, the screen illuminating your face in the dimly lit concert hall, filming Yeonjun, another member of TXT. The camera panned across the stage, capturing the intricate choreography and the raw energy of the performance.

Suddenly, a shadow loomed over you. Glancing up, you saw Taehyun standing right beside Yeonjun, who was unaware of the brewing tension. Taehyun's face was a mask of jealousy—his jaw tight, brows furrowed, and his tongue peeking out of his cheeks. The bright stage lights caught the subtle flush of his neck, visible even from your position in the audience.

The sudden change in his demeanor took you by surprise, a shiver running down your spine as the bass from the speakers vibrated through your body. Taehyun's jealousy was a rare sight in the two years you've been together, and it left you wondering how he'd react, the intensity in his expression a stark contrast to his usual sweetness.

Taehyun knew that he couldn't act jealous in front of millions of fans, and he had to maintain his professional composure. But his eyes never left you, tracking your movements like a hunter stalking prey. The scent of sweat and cologne mixed with the faint smell of popcorn from nearby vendors wafted toward you.

As the song transitioned to a slower bridge, Taehyun stepped back, his eyes never leaving you, as if he was claiming ownership. He then looked at another fan with a practiced smirk that didn't reach his eyes, before rejoining the performance, his movements sharp and precise, almost aggressive compared to his usual fluid style.

"Just you wait." he muttered into his microphone, the sound not picked up by the audio system but visible in the movement of his lips, before acting like nothing had happened.
