Based on a classic Chinese line: 'Better waste time not辜负岁月，也不要辜负人（宁愿浪费时间，也不愿意亏欠他人）。Here the word “流年” represents the time spent in youth. The whole phrase implies choosing to remain loyal or true to a significant individual even at the expense of wasting youthful prime time. It expresses the value orientation to keep the sincere love despite difficulties and changes.
