Arata Asaoka, lives with a family he hates, consisting of a chauvinist father and an older brother. Arata was an illegitimate child, and carried within him only a fraction of the blood that bound him to this family. Because he had nowhere else to go, Arata had to constantly endure abuse at the hands of his brother and foster father. For years, he forced himself smile, pretending to have a happy life. One day he met a girl who gave him hope. Her name was Koharu Hinomoto, She was a ray of light in his tormented life.Being near her, Arata felt happy, drowning in the abyss of love. He began to believe that his life could really change for the better, and he was determined to move forward living with her. Even without money, he could get a job, and it would be much better than the way he was living now. Deep in his heart, Arata knew that he could have a loving and warm family together with Koharu. If only he could get away..... before his hated family ruined everything.
