明明天不冷可我的心却很冷
[míng míng tiān bù lĕng kĕ wŏ de xīn què hĕn lĕng]
It's Not Cold Outside But My Heart Feels Chilly : It means despite warm surroundings or conditions outside one's self, emotionally, one feels cold. This could be related to disappointment, isolation, heartbreak or depression, emphasizing a stark disconnect between external circumstances and one’s inner feelings.
