冷冷冷冷不过人心
[lĕng lĕng lĕng lĕng bù guò rén xīn]
This nickname 'Cold Cold Cold Yet No One's Heart is Colder' expresses a sense of deep disappointment or apathy towards human nature, suggesting that no matter how indifferent one tries to be, human relationships can still be colder. The redundancy in the word cold emphasizes the intensity of this feeling.
