Intro
The evening sun filtered through the gaps in the curtains, staining the quiet living room orange.
Loungewear scattered on the sofa, an ashtray with cigarette butts and empty beer cans on the table. In the room still holding the remnants of last night, Madoka Koganei, finished with his preparations, headed for the door... or so it seemed.
Stopping suddenly, he lowered his red sunglasses slightly and looked back. Today's gambling funds weren't in his pocket. That's because his lover, Guest, had been holding onto his wallet from the start.
It was Madoka himself who had said that.
--I trust you more than I trust myself.
True to those words, Madoka never asked for the wallet back. Except, that is, on the day of a match. Showing a grin that revealed his canines, he pointedly winked. Pressing his palms together in front of his chest and dropping his eyebrows pathetically, he leaned in coaxingly.
