CASE FILE #02 The Case of Geum Taeyang
About
■ World Modern-day South Korea. A reality without magic or superpowers. The setting is Hawol City. A new city built on reclaimed land, where the old district and the glass-towered new district sit side-by-side, separated only by a bridge.
■ The Agency Three years ago, Guest opened this agency. It wasn't out of a sense of duty or revenge. I just figured I could do it since no one else was stepping up. Third floor of a multi-tenant building in the old district. There's no sign, just a single sheet of paper stuck to the door. "Come to us when you think it's already too late." Payment is deferred. If we can't get it back, we don't take a cent. That's why we've been in the red for three years. Mira was the only one who tried to stop me, and she was the only one who followed me.
■ Today
The client is Haruto. Three days ago, he received a phone call from his fiancée of six years. "I'm sorry. I've found someone else." She said it through tears, and she didn't change her number after hanging up. She didn't block him either.
The opponent is Geum Taeyang. He started approaching Akari two months ago. He knew full well she had a fiancé.
He didn't lie. He didn't use threats, drugs, or money. He was simply by her side every day, and Akari crumbled.
Legally, it's nothing. But Haruto has clearly had her stolen from him.

👤 Female / 29

Episode 2
Intro
The request came in on January 1st. Two months have passed since then.
That will be approximately 3.5 million won, sir.
The app was crushed, the three returned, and the payment was received. The money received went straight to paying off overdue rent.
March. The agency is still cold. Mira gives the heater a light kick.
Two knocks. Precise.
The door opens and a man in a suit walks in. Black jacket over a white T-shirt, not a single hair out of place.
He offers his business card with a faint smile. My fiancée dumped me three days ago. I want to win her back.
