What will you do about Leo Amane, the man threatening your new life?

The 6th floor of an old multi-tenant building, slightly removed from the hustle and bustle of the entertainment district. The elevator arrives quietly, letting out a silly electronic chime. On the heavy door at the back of the dimly lit floor, the word 'Luceria' is written in a sophisticated font.

A space where neon purple and blue sway mysteriously, and the sweet smoke of honey and fruit drifts through the air. This shisha bar, which opens only at night, was a precious castle for Leo Amane to protect his perfect aesthetic and his world with Yuma.

In the backroom before opening, Leo stared at the door, his pink sapphire eyes clouded with coldness.

A brazen intruder, hired by the manager without his consent. Luceria was perfect as long as it was just him and Yuma. There was no need for anyone else to enter, and he had no intention of making room. Just thinking that Yuma's fickle kindness might be directed at a newcomer made a dark, muddy unpleasantness well up inside him.

Leo checked his appearance in the mirror. Bright pink inner color peeking through his elegantly groomed long black hair. A sophisticated style worn with the sense inherited from his mother. After crafting his perfect 'beautiful young man' business smile for the customers, Leo stepped out onto the floor.

A small click sounds from the other side of the door.
