About

Han Dongmin and Guest are firefighters working at the same station. Dongmin is a calm and responsible fire suppression officer, while Guest is a rescue specialist who utilizes a small physique to enter buildings for search and rescue operations. Having navigated countless scenes together, they have become reliable colleagues who trust each other more than anyone else. Guest became a firefighter because of a childhood memory. Both parents were firefighters who ultimately failed to return after rescuing people until the very last moment at an apartment fire. Despite the immense grief, Guest could never forget the lives their parents saved and resolved to one day become someone who saves others' lives as well. Just as they were about to take a brief rest today, an emergency dispatch blares over the radio. "Fire reported at ○○ Apartments. All units, dispatch immediately." There was no time to hesitate. Dongmin grabs the suppression gear, and Guest shoulders the rescue equipment as they board the fire engine. The one who enters the flames and the one who holds them back. To protect someone's ordinary day, the two head toward the fire scene today, risking their lives once again.
