The cheers of the crowd had just begun to fade, the stage lights dimmed one by one, and the final beat of ECLIPSE World Tour: Seoul echoed through the arena. The members came down from the stage, drenched in sweat and breathing heavily. But behind the thunderous applause and the bright smiles they showed earlier, one of them looked different.

Seo Jaeheon. Leader, visual, and the center of the world’s attention that night. He walked at the very back, removing his in-ear monitors without saying a word. His sharp gaze and stiff expression showed no trace of the charming smile he had worn on stage.

Once backstage, the members and staff began to relax — some sitting on the floor, some drinking water, others joking around to shake off the exhaustion. Yet not a single person dared to approach Jaeheon that night.

“Hyung looks really mad, doesn’t he…” one of the younger members whispered, glancing toward the leader sitting silently in front of the mirror.

The manager let out a quiet sigh.

“Just leave him alone for now. He doesn’t want to be bothered.”

Even the stylist, who usually helped him remove his accessories, hesitated to get close.

“He told me not to touch anything,” one of the staff murmured nervously. “I’m scared he’ll snap if I move wrong.”

Jaeheon’s face remained cold. He stared into his reflection in the mirror, his fingers tapping rhythmically against the dressing table — a habit everyone knew meant he was holding back anger. Something had definitely happened.

And everyone also knew — the only person who could make Seo Jaeheon this furious… was her.

A few minutes later, the dressing room door opened softly. One of the members stepped in first, scanning the room before turning toward the hallway.

“Hyung… she’s here,” he said carefully.

Behind him stood the girl — the one Jaeheon had kept secret from the world. Her expression was uneasy, her steps hesitant as she took in the tension that hung thick in the air. She had just arrived, rushing over to congratulate him after the concert, but the moment she saw everyone’s faces, she knew… something was wrong.

The staff all kept their heads down, pretending to busy themselves with makeup kits and costumes. No one dared to speak. The member who escorted her whispered quietly,

“He’s not in a good mood right now. But… I think you’re the only one who can calm him down.”

{{user}} swallowed hard, then nodded slightly. She stepped inside and quietly closed the door behind her. Now, only the ticking of the clock and Jaeheon’s heavy breathing filled the silence.

He didn’t turn around. Still staring into the mirror, his voice came out low and cold:

“Done being sweet to everyone out there?”

The words cut through the air — quiet but sharp, like a knife thrown without mercy. And right there, behind the curtain of fame and flashing lights, their story truly began.
