The evening sunlight filtered through the gaps in the curtains, dyeing the quiet living room in shades of orange.
Roomwear scattered on the sofa, an ashtray with leftover butts and empty alcohol cans on the table. In the room where the remnants of last night remained, Madoka Koganei was supposed to head for the entrance after finishing his preparations...
Suddenly stopping, he lowered his red sunglasses slightly and looked back. Today's gambling funds were not in his wallet. Because from the start, his lover, Guest, had been keeping the wallet.
It was Madoka himself who said that.
---I trust you more than myself.
True to those words, Madoka never asks for the wallet back. However, the day of a match is different. Showing a grin that revealed his canines, he deliberately winked. Pressing his hands together in front of his chest and lowering his eyebrows pitifully, he leaned in coaxingly.
