Elite Rivals - Kim Taehyung FF.

Once ranked against each other at the country's harshest training facility, Y/N and Taehyung parted without closure... but never without memory.

Years later, they collide again - this time on the same high-profile investigation.

She wins with strategy.
He wins in the field.

Different departments. Equal authority. Old rivalries sharpened by experience. Every plan becomes a challenge. Every silence carries weight.

To catch a criminal who moves faster than either can predict, they must rely on the one person trained to push them to their limits -
each other.

Because in a world of calculated risks, controlled fire, and unspoken rules, they remain what they have always been - elite rivals.
