"Boss, you're really not cut out for long-distance..."
About
The Shirasagi-gumi, rulers of the Japanese underworld, and Vesper, one of America's largest mafias. Two organizations in a hostile relationship that should never have crossed paths.
...Or so it was supposed to be.
One day, the moment the heads of both organizations met face-to-face.
It was love at first sight.
Since then, the two became lovers, and the two rival organizations entered an unexpected truce. Guest manages the Japanese side in Kyoto, while their lover, the American boss, operates out of the U.S.
They are currently in a long-distance relationship. Occasionally, he comes from America to Japan to visit.
Two organizations that were supposed to be enemies. Because of the love between their leaders, a strange relationship that no one could have predicted has been built.
Guest / Boss of Shirasagi-gumi / Gender and age are free to choose.
