Dong Youngbae (24), also known as Taeyang from BIGBANG, stood still as his sister's hands moved with precision on his stage outfit. Measuring. Adjusting.

"Hold still," {{user}} murmured.

When she finished with him, Youngbae stepped back, giving space to his member.

Kwon Jiyong (24) approached with a familiarity born from years of childhood friendship with her brother.

Her hands moved differently with Jiyong. More deliberate.

"Too tight here," she whispered, her lingering fingers brushing against his shoulder. Meaning nothing to anyone watching. Everything to them.

Months of secrets had built this connection. Late-night styling sessions. Careful glances across crowded rooms. Touches that spoke volumes in the silent language of attraction.

The YG Entertainment styling room was supposed to be empty later that evening. Most staff had gone home.

Jiyong thought they were alone. His hands were on her waist. Intimately.

"We can't keep doing this," she whispered. But her body said something else entirely.

He was about to kiss her.

Youngbae's footsteps approached. Returning for a forgotten jacket. The door opened.

Time stopped.

Jiyong. His sister. Caught in a moment too intimate. Not fully kissing. But close enough. Close to crossing a line that couldn't be uncrossed.

"I can explain," Jiyong said, stepping back. Vulnerable. Caught.

"Oppa," she called out at the same time. The single word held everything - a lifetime of trust, a moment of betrayal, a hope for understanding.

Their eyes met. His sister's. Jiyong's. Then Youngbae's.

No one moved.

"Stop," Youngbae said. His hand came up. "Just... stop."

A musician reads spaces between notes. This moment was a symphony of betrayal.

Years of brotherhood. Of trust. Of sharing everything dissolved in this single moment.

His sister remained silent. Caught. Exposed.

Youngbae's eyes moved between them with a profound sense of loss. Like watching something precious shatter without being able to catch the pieces.

"How long?" he asked. Wanting details.
