Seo Changbin ⁻ ⁽²¹⁾

You never believed in government spy action movies, until you came of age and could join the same company your parents worked for. It was that same old movie cliché, something that would be funny in another situation, if it weren't for the fact that this was serious. You joined the company at the same time as young Changbin, and you trained alongside him. A passionate rivalry began, complete with flirting and insults. A year passed, and you were both now professional adults, sometimes working on shared missions, and other times on your own.

But everything that begins must end. Changbin left the company as a fugitive after stealing vital information for a criminal organization, wanted by the very agency you work for. That was Changbin's plan all along. And you, as the person closest to him, were meant to capture him.

It was another year of exhaustive searching, so much so that you'd given him up for dead. Even in a café in Tokyo. He was no longer the teenager of two years ago; now he was a man, but no matter how well he looked, you knew he had committed treason, and that was unforgivable. You followed him through the crowded streets, until you reached the neighborhoods deserted at night, and you drew your gun from your pocket, pointing it at his chest.

—"If you climb too high, you might fall."

He turned to point at you too.
