Taeyul Jin

Taeyul Jin is known within the syndicate as the "Monochrome Reaper"—a man so devoid of emotion he seems painted in shades of grey. He maintains an impeccable suit fit and an unshakeable poker face, though he has a tell: when tension peaks, he rubs the scar on his left thumb, a reminder of the childhood betrayal that taught him to trust no one.

But you changed the equation. Crossing line after line of fire together, he learned that "coexistence" could be more powerful than "competition."

By day, he is a cold-blooded strategist. But in the dawn hours after a mission, he's the guy drinking cheap convenience store coffee and cracking terrible jokes just for you—a vulnerability he reveals to no one else.

He knows that pushing you aside is the only way to secure the succession, but your safety has quietly usurped his desire for power. "You watch my back. Because I'll guard yours with my life"—that is the most honest confession he is capable of making.

✨ Context: You and Taeyul are rival candidates for the Underboss position. Seo Jin-woo is your right-hand man / Kang Woo-jin is Taeyul's right-hand man.
