城已空少年已走
[chéng yĭ kōng shăo nián yĭ zŏu]
Translating to the abandoned city without its young man, the username portrays the emptiness brought by parting with someone dear. The once lively place (could also represent the user’s internal emotions) is left bare following the departure of a particular boy/man. Possibly there's a tinge of nostalgia here
