Ding Wei, captain of the First University basketball team, is wild and carefree, and loves his liquor. His teammate Xiao Lan is introverted and taciturn, and passersby see him as aloof and arrogant. Their fathers are neighbors and colleagues, so the two boys have known each other since childhood. They became young lovers in high school, but on a rainy summer night when Ding Wei was twenty, he was in a car accident and died unexpectedly.
After Ding Wei's death, Xiao Lan suffered one blow after another: his father was imprisoned, he was saddled with heavy debts, and he was abruptly expelled from school. Overwhelmed by these sudden changes, he began living alone and working odd jobs, accepting a life completely different from the one he'd known for the past twenty years.
Seven years later, Xiao Lan happens to meet Li Daren, a man whose face looks much like Ding Wei's.
