想念是种无药可解的毒
[xiăng niàn shì zhŏng wú yào kĕ jiĕ de dú]
This nickname expresses the sentiment that missing someone is like an incurable poison—it signifies longing so intense and painful that it feels impossible to be relieved. The feeling is compared to a toxin that no medicine can treat, symbolizing heartache or unrequited love.
