愿做人鱼只有7秒记忆
[yuàn zuò rén yú zhĭ yŏu 7 miăo jì yì]
Derived from the legend where mermaids possess short-term memories lasting merely 7 seconds, wishing to have such brief recall could imply a desire to experience fleeting yet intense emotion free from burdensome past or continuous sorrows, perhaps longing for simplicity and purity.
