你以为我百毒不侵我以为你刀枪不入
[nĭ yĭ wéi wŏ băi dú bù qīn wŏ yĭ wéi nĭ dāo qiāng bù rù]
This name implies the idea that both individuals in a relationship thought they were immune to harm from one another, but reality proved otherwise. Each thought the other could endure any hardships or tests, reflecting the disillusioned realization that their defenses against emotional pain were not as strong as expected.
