The coming-of-age story of three girls. They were good friends when they were students. After going through the college entrance examination, going abroad, falling in love, and working, they grew from little girls into independent and optimistic women. Growth is interspersed with confusion, sentimentality, and hesitation, as well as surprises, miracles, and warmth. Just like Faye Wong's "Human World": I hope your eyes can only see smiles.
