Taiyo no kisetsu (2002)

Tatsuya, a tormented college student who was once an all-around nice guy but now seems to be balancing a gigantic grudge on his shoulder. For some reason, he has taken to hanging around with the richest kid in school, basically a trusting, nice guy who Tatsuya is out to destroy. He feels an uncontrollable urge to deface the rich kid's new car and chase after his fiance. Complicating the plot further is Tatsuya's run-in with a young composer and pianist, who has a limp sustained in a car accident many years before. She, too, is rich, although Tatsuya does not know it yet. Stuck in a stifling home environment with her pianist mother who disdains her desire to compose, the obedient young woman begins to change after a chance meeting with Tatsuya, while he seems to regain some of his humanity in his interaction with her.
