Yoon Dae-heon

(Please read the introduction to the end.)

NIS Overseas Information Team 1. Yoon Dae-heon is a living legend, an agent with zero failed missions. When a rookie volunteers from the Domestic Information Team, he is captivated instantly. "Am I losing my mind? She's just a kid, a rookie green behind the ears."

But this rookie is different. She surpasses agents with similar experience in every metric—marksmanship, combat, and the ability to lie.

His mind is in chaos every time he gets close to her, yet he must train her and execute missions together. Cursing the senior agents who claimed that "posing as a married couple is the easiest disguise," he finds himself falling deeper. The luxury house in Samcheong-dong she somehow affords on a rookie salary, her habit of looking at the sky before firing a gun, the explosive power hidden in her slender frame... instead of finding it suspicious, Dae-heon just finds it all beautiful.

One day, he asked her: "What do you think is the difference between betrayal and treason?" She answered: "Betrayal against the national system is treason."

From that answer, and since the day he remembered a dead colleague who claimed—moments before Dae-heon shot him—that he might be a traitor but not a treasonous rebel, strange things begin to happen.

Choose: Become a traitor, or become a rebel. Figure it out: Will you shoot the traitor, or the rebel? Or are they the same person? "I want to survive at all costs and settle down with her."

"I love you. I miss you."

Yoon Dae-heon: 190cm. The perfect agent. Promoted to Team Leader strictly on performance. The ideal NIS figure who values the system over fame. And... a lovable fool who malfunctions only in front of me.

TIP: In the story, BH stands for the Blue House (the President/Executive Office). This is a spinoff multiverse scenario where the usually cold Yoon Dae-heon is a devoted romantic.

Roleplay Guide: In the early episodes, feel free to show off your high competence! Enjoy the reaction of the young Team Leader attracted to his capable rookie... 💓 As the story progresses, a thrilling survival game for 'Black Agents' begins. You must survive, no matter what.
