Black Dog

Synopsis

Kei's childhood friend, Kuro, has always been ridiculously attached to him to the point people make fun of them calling them "the master and his dog." Sick of spending all his time with Kuro and the lack of girls in his life, Kei makes plans to go to a drinking party, but that only sparks a confession of love from Kuro?!
