He , who could not be defined by a simple keyword , or a meaningless textbook definition . He was wrapped up in his own world , filled with black and white , no color , no meaning . Just filling the days with something useless to ignore the pain in his heart . Until she came along with a burst of color , wild hair , loud mouth , and curious green eyes , suddenly putting meaning back into his meaningless life . She could not be defined , by any definition , any keyword . This is the story of how two people made each other's worlds meaningful , and ever more so undefined .
