衍夏成歌离人未归
[yăn xià chéng gē lí rén wèi guī]
'衍夏成歌离人未归' evokes the imagery of a melancholic summer. This username paints a poignant picture where beautiful memories and music ('songs of summer') remain but the person you love is absent or has left ('no return of the wanderer'). It reflects longing and nostalgia, possibly indicating someone missing an important loved one.
