Hua Er Gong Detective Agency

Huacheng Metro, Second Workers' Cultural Palace Station, commonly known as Hua'er Gong.

There's a small private agency in front of the station. It specializes in finding missing people, but also takes on jobs like tracking down lost items and pets or catching cheating husbands.

For all those petty cases the authorities won't take, you can pay to get them handled here. This is a long-established business with a good reputation

Song Liuxing is the agency's star investigator, as well as a single mother.

She and her elementary-school-aged child live in cramped quarters on the agency's top floor. Every day she wears a bright smile, braves wind and rain, and solves the neighborhood's problems, always delivering on her promises.

No one knows where she came from.

No one knows that on a small island in the South Seas stands a secluded mansion, built a century ago by a wealthy merchant in exile. Carved rosewood phoenixes, piles of gold and pearls: its extravagant splendor could dazzle anyone.

Song Liuxing was only a servant's daughter, yet she dared to fall in love with the mansion's sole young master.

Song Liuxing herself has deliberately tried to forget.

So many things ended in tragedy. She had long since decided to leave it all behind and live a different life.

Sometimes the past comes back to her, but even the face of the young man who once broke her heart has faded until she can barely make it out.

One day, Song Liuxing attends a school family event and meets the uncle of her child's classmate.

He's tall and handsome, with an imposing air, but there's something inexplicably suspicious in his eyes, as if he's forcibly suppressing something.

Even more suspiciously, this uncle goes through the agency's owner and strong-arms his way into a job at the agency!

After years of working alone, Song Liuxing begins a two-person partnership that sets her heart racing.
