七堇年华不负君三寸季光不忘卿
[qī jĭn nián huá bù fù jūn sān cùn jì guāng bù wàng qīng]
'Seven years' blossoming youth has never been unworthy of you; three inches of seasonal light has never forgotten you.' It beautifully encapsulates the essence of youthful devotion. The person may value deeply held memories or promises of love that span years. They cherish their youthful exuberance and the time spent loving someone fervently.
