❝Two Agents. One Mission. Zero Patience.❞ Kang Sena-calm, observant, and just the right amount of cranky-is one of NIS Team 1's top agents under the sharp leadership of Kong Jin Sang. Precision is her expertise, and she takes her missions seriously-until Team 4 gets involved. Jung Hae Seong, a spontaneous, reckless problem-solver from NIS Team 4, led by An Seok Ho. If there's a fight, he's in it. If there's a mystery, he's solving it. And if there's an opportunity to one-up Team 1? He's definitely taking it. For years, Team 1 and Team 4 have been rivals-constantly watching, waiting, and ready to call out each other's mistakes. So when Director Kim Hyeong Bae forces Sena and Hae Seong to go undercover as high school transfer students, neither of them is thrilled. A fake friendship? Impossible. Blending in? Disaster waiting to happen. Surviving high school together? ...They'd rather take on a criminal organization. But with a mission on the line and no way out, the real question is: Will they take down the enemy first... or each other?

In which twin siblings Gamin and Gaeun enter Yusung Technical High-Gamin chasing college dreams, Gaeun protecting him. There, she clashes with Pi Hanwool, a cocky fighter, but their rivalry sparks something deeper. In a school ruled by violence, can love survive the fight?
