DONT READ THE THIRD CHAP D O N T. DONT. but! the following is the story of straight bartender A who works at a gay bar, and kind of picky yakuza head B, that likes him. A gets stuck in some debt cause of a shitty friend and B gets him out of it, but the catch is that A turns into his personal toy. pretty simple.
