柠檬菇凉柚稚少年
[níng méng gū liáng yòu zhì shăo nián]
The nickname "柠檬菇凉柚稚少年" (lemon girl and youthful boy) evokes imagery of two young people: a fresh, perhaps somewhat tart 'lemon girl' symbolizing purity or slight sourness that comes with growing up, alongside an innocent young boy ('youzhi shaonian'). It conveys youth, innocence, and the freshness often associated with young love or adolescence.
