百毒不侵其实早已万箭穿心
[băi dú bù qīn qí shí zăo yĭ wàn jiàn chuān xīn]
The saying 'immune to all toxins but has been stabbed by countless arrows' illustrates a paradox between outward resilience and hidden pain within oneself; this name suggests someone who pretends to be immune to all harm or heartbreak but actually bears unseen scars and suffers internally.
