别回头哥恋的只是你的背影
[bié huí tóu gē liàn de zhĭ shì nĭ de bèi yĭng]
'Don't Look Back, My Love for You is Just Your Silhouette'. This captures a bittersweet emotion where someone remains in one’s memory solely by the form their back figure leaves behind. The lover expresses not needing anything but the beloved person's silhouette.
