尖锐又怕受伤的刺猬
[jiān ruì yòu pà shòu shāng de cì wèi]
Translated as 'The sharp hedgehog afraid of being hurt', this suggests a protective yet sensitive personality. Just like a hedgehog has spines that serve as a defense mechanism, the user might put up a front of confidence or hostility to protect themselves from being hurt emotionally.
