心如暮光天然暖心如时光天然凉
[xīn rú mù guāng tiān rán nuăn xīn rú shí guāng tiān rán liáng]
'The heart warms like twilight, but also naturally cools like time passing.' This poetic expression describes feelings changing over time: warmth and closeness turn cool with the passage of time, mirroring the natural ebb and flow in relationships or one's inner feelings.
