Everyone is born with a flower. That flower controls your life. If its black your soul mate is the same gender as you, however, it also means that you possibly commit self-harm and/or are abused. Yamaguchi Tadashi has never had a happy childhood or a good life in general. With a flower as black as black can get he is alone. Tsukishima Kei has no friends and never wants any. He is alone by choice with a black flower on his wrist. With a happy childhood and people who care about him, he is alone by choice. But happens when these two polar opposites meet in the most cliche way possible? Will Yamaguchi finally have a friend or is Tsukishima just like everyone else? And will Tsukishima accept the new green haired boy? Or will he just give him the cold shoulder like everyone else?
