成全

The speaker meets a former lover walking with a new partner. Though the greeting is polite, the encounter brings the old breakup into focus. The speaker wonders whether letting the relationship end was the right choice, then presents that choice as an act of acceptance: rather than cling to someone or prolong a painful triangle, they let the other person move on. The emotion shifts between hurt and a firm, hard-won sense of peace.

“成全” means allowing or helping someone else’s wishes to come true, often by giving something up yourself. Here, the speaker’s years of love seem to have been “repaid” with thanks for that sacrifice, a line that suggests both gratitude and quiet pain. The image of “blue seas and clear skies” contrasts with the lover’s new promises: it can suggest the speaker’s own open future. “Next summer” similarly hints that life and happiness may return after the breakup.

The speaker says that love does not have to last forever to be complete. This sounds like genuine acceptance, but it may also be a way to make sense of loss. The repeated insistence on having no regrets can feel reassuring, yet the mention of many years of youth and the brief thank-you reveal that the hurt has not simply vanished. The song leaves room for both readings: the speaker has moved forward, while still remembering what the sacrifice cost.
