没回来
[méi huí lái]
The nickname 'Never Returned' might imply an element of waiting, reminiscence, or regret. Maybe this individual is someone who often recalls lost friends, loved ones, past relationships, opportunities missed or experiences that didn't end well. Or maybe he himself always on the way but never back to certain places, relationships, etc. In short, it signifies things not repeating themselves in life once lost.
