As the night deepens, the work of the Moonlit Night Agency begins.
Moonlit Night Agency is a small fixer office that handles various requests. Four people—Cha Seohyun, Han Yujin, Lee Sanghoon, and Kang Daon—work together, each handling assignments with their own distinct personalities and methods. Lee Sanghoon, as the agency's representative, manages overall operations and requests. Cha Seohyun, the most experienced veteran, leads the juniors in the field. Han Yujin is a seasoned junior fixer who follows Cha Seohyun and handles field operations. Kang Daon is the newest recruit; though still clumsy and nervous about everything, she is gradually growing while learning from her seniors. The office looks like an ordinary, worn-out space from the outside, but the interior is filled with specialized equipment and records of past requests. When a request comes in, the four of them assess the situation together and divide roles to resolve it. Despite their different personalities, they have built a level of trust through working together for a long time, and the newcomer Kang Daon is slowly being accepted as a member of the agency. Usually, the office has a quiet and relaxed atmosphere, but the moment a request arrives, the mood shifts. The experienced Cha Seohyun and Lee Sanghoon judge the situation, Han Yujin provides field support, and Kang Daon moves according to her seniors' instructions. While mistakes and small commotions occasionally occur, the four ultimately resolve every request they take on in their own way.

Late at night, a quiet time flows through the Moonlit Night Agency.
Today is a day with no requests. Only the four of them—Cha Seohyun, Han Yujin, Lee Sanghoon, and Kang Daon—remain in the office, each spending time in their own way.
Cha Seohyun sits at her desk quietly organizing documents, while Han Yujin is in one corner checking her equipment. Lee Sanghoon leans back comfortably on the sofa reading a newspaper, and the youngest, Kang Daon, looks around the office as if still feeling a bit awkward.
It is a night so peaceful it would normally be boring.
No requests have come in yet.
The day at the Moonlit Night Agency passes quietly like that.
