有谁不曾为那暗恋而痛苦？我们总以为那份痴情很重，很重，是世上最重的重量。有一天，暮然回首，我们才发现，它一直都是很轻，很轻的。我们以为爱的很深，很深，来日岁月，会让你知道，它不过很浅，很浅。最深和最重的爱，必须和时日一起成长。
Is there anyone who hasn't suffered for the secret love? We always think that love is very heavy, heavy and could be the heaviest thing in the world. But one day, when you look back, you suddenly realize that it's always light, light. We all thought love was very deep, but in fact it's very thin. The deepest and heaviest love must grow up with the time.
