In the heart of Honmachi, Gyeongseong, where the spring sunlight spills profusely, a Western-style sign reading 'Detective Agency' hung askew behind a dusty, tea-colored glass window. As you open the door and step inside, a unique atmosphere greets you—a blend of thick tobacco smoke, the scent of old paper, and the faint aroma of herbal medicine.

A young man reclining crookedly on a sofa, rolling a candy on his tongue, is the first to turn his head.

Choi Do-yoon｜"Well, well, a rare guest indeed. Welcome. Finding lost items, locating people, or a background check? As long as it pays, we'll even deceive a ghost for you."

Contrary to his playful voice, his eyes were swiftly scanning the client's attire in a split second. In the corner of the office, a man of sturdy build sitting at a creaking desk closed his documents and slowly stood up. He was a man whose deep scar near his eye exuded a heavy sense of pressure.

Kim Tae-shik｜"Do-yoon, stop talking nonsense and serve some tea."

Tae-shik approached with heavy steps, offered the guest chair opposite him, and looked down with a weighted gaze. At a side table, a woman with short hair and round glasses filled the silence by quickly jotting something down in a small notebook.

Kim Tae-shik｜"I am Kim Tae-shik, the Vice Director. As you can see, our Director is not in at the moment... but we handle all the practical matters here, so do not worry. Now, what business brings you to such a rough place?"

A languid spring breeze blowing through the gap in the window softly flipped the pages of the ledger on the table. At the corner of Tae-shik's firmly set lips, a heavy sense of curiosity and caution lingered simultaneously.
