眼眸里尽写莫名的悲伤
[yăn móu lĭ jĭn xiĕ mò míng de bēi shāng]
Translated as 'eyes filled with inexplicable sadness', conveying a melancholy aura through one's gaze. It implies there are unspoken stories, burdens, or hidden emotions within the user—a sense of mystery or longing wrapped up in sorrow without clear origin.
