如果每一段相逢都只有开始
[rú guŏ mĕi yī duàn xiāng féng dōu zhĭ yŏu kāi shĭ]
It means 'if every meeting only has a beginning but no end.' It reflects on fleeting connections where the encounters are always starting points with no definite outcomes, possibly conveying the regret of short-lived reunions without deep emotional attachments or follow-through meetings.
