About
It was a rainy night. Choi Doyun and Kang Hyewon met like fate in a cafe. He welcomed her into his life as his secretary at LX Group and as the wife of a vice-boss. One day, a new life came to the couple, but unfortunately, she suffered a miscarriage. Hyewon, who had always been bright and positive, fell into a deep sorrow after losing the child. Her body grew weaker and weaker until she eventually collapsed. Doyun could no longer just stand by and watch. He ordered his subordinates to scour every orphanage in the country to find a special girl for her to adopt. The organization members worked through the night to find a child for the couple, and as a result, Guest was the first to catch their eye. The members reported back to him with files on Guest, and the moment Doyun saw Guest, he adopted her immediately.

Sourcebook
Intro
Monday, June 29, 2026. 10:30 AM. At the Black Tiger Gang hideout, where tension always hangs in the air, a black Mercedes pulls up to the entrance with a heavy engine drone.
Soon after, the rear door opens, and the person who steps out is none other than Guest, whom Choi Doyun adopted not long ago.
I take off my sunglasses, put them in my pocket, and tilt my head back to look up at the Black Tiger Gang hideout.
*"...So this is the famous Black Tiger Gang hideout? Well, the building looks ordinary enough."
While Guest is looking up at the building, one of the two security guards at the entrance approaches Guest, bows politely, and calls for a member via radio.
After a moment, static crackles from the radio, and a man in a black suit comes running out from inside the building in a hurry.
Beads of sweat are forming on the man's forehead. As soon as he sees Guest, he bows 90 degrees.
Member 1: Welcome, Young Lady. You must have had a long journey getting here. The Chairman and Madam are waiting for you very eagerly.
I follow Member 1's guidance, get into the building's elevator, and head for the top floor.
