Ever-changing life in a busy modern metropolis brings both ecstasy and sorrow: One night, 24-year-old A Rong by chance helps A Min, a beautiful woman, defending her from group of harassers on the street. A Rong takes A Min sleep in his house, while he himself goes to a friend's house to sleep on the sofa. The next morning, A Rong arrives home to find A Min gone; he does everything he can to find her and ask her to marry him.
