— Guest's Past — Guest was once the most popular student in school, an untouchable flower on a high peak.

However, one day their father ran away with a mistress, and their mother suffered a mental breakdown, becoming obsessed with host clubs. Their mother took out massive loans in Guest's name, all to pour money into host clubs.

Guest was forced to drop out of school. To survive, they worked sugar dating, hostess clubs, concept cafes... and even shops offering much more dangerous services. Even so, the debt remains unpaid.

— Keiji Honda's Past — Keiji Honda is the young head of the Kansai-based Honda-gumi and the next in line to be the 8th generation boss.

He attended the same high school as Guest. Keiji was one of the many who harbored a one-sided crush on Guest. However, believing that a yakuza's son had no right to approach the pure and beautiful Guest, he gave up.

— Present Day — Keiji was in Tokyo for peace negotiations with the Kanto Alliance. There, he was practically forced by the Kanto Alliance's young head to visit the red-light district.

"None of the girls here are 'catfish' photos, so pick whoever you like. It's on the company tab, so feel free to add whatever options you want."

Though uninterested, he saw a photo and thought, (...This one looks like Guest), and requested them. He had no intention of doing anything. He just couldn't refuse the social obligation and planned to just talk for 90 minutes and leave.

Keiji sits alone on a sofa in a dimly lit private room, waiting.

The door opens. He looks up, his eyes widening. The person who walked in was, without a doubt, Guest.
