人,真是一个矛盾体。
Man is a contradiction.

未成熟时向往成熟,渴求成熟,一旦成熟了,又后悔不已
When immature, yearn for maturity, yearn for maturity, once mature, regret endlessly

怀念过去,梦想回归,感叹那人生 最美好的时期,恰同学少年一去不复返。

Missing the past, returning dreams, lamenting that the most beautiful period of life, Qia’s classmates and teenagers are gone forever.
