Tomoya Okazaki is a third year high school student who dislikes his life. However, Tomoya finds that his life is about to change when he meets Nagisa. Tomoya's mother Atsuko died when Tomoya was young, leaving his father Naoyuki to raise him. After the accident, Tomoya's father turned to alcohol and gambling, and held frequent fights with his son. One day, Naoyuki, again arguing with his son, slammed Tomoya against the wall, dislocating Tomoya's shoulder. Ever since then, his father has treated Tomoya nicely, but distantly, as if Tomoya and he were strangers rather than a family. This hurts Tomoya more than his previous relationship with his father, and the awkwardness of returning home leads Tomoya constantly to stay out all night.
