Clannad

Tomoya Okazaki is a disaffected high school senior who feels stuck in life. After his mother died in a car accident years ago, his father turned to drinking and smoking, leading to constant arguments between them. One fight left Tomoya with a shoulder injury, deepening the rift between father and son. Over time, Tomoya grew distant and fell into delinquency. One morning on his way to school, he meets Nagisa Furukawa, an unusual girl a year older than him who is repeating her senior year due to illness. Isolated after her classmates moved on without her, she spends most of her time alone. As the two start spending time together, Tomoya gradually feels his life taking an unexpected turn.
