Furitani Haruaki feels that he is the luckiest person in the world because he has a well-behaved, smart, smart, and lovely younger brother who calls him Onii-chan, and a lover who is cold on the outside but warm on the inside, considerate and gentle, and who loves him deeply and will take care of him in every possible way.
The only bad thing is that his lover and brother always wear black because of work. And black... Is the nemesis he must kill - the favorite color of an organization whose members are all codenamed after alcohol, so the color he hates the most is black.
But as an excellent lover and an excellent brother, no matter how much he hates black, he will not hate his lover and his brother's work because of it. He will only support them silently behind their backs.
Until one day, Shirouya Seimei saw two senior cadres of the organization captured by his subordinates - an excellent blond and dark-skinned intelligence officer of the organization code-named Bourbon and a silver-haired man code-named Gin known as the Top killer.
Fukitani Seimei calmly rubbed his brows and stared blankly at the sky above his head. Who can tell him why the people in these two organizations look exactly like his lover and brother?
