我在你心却不久居
[wŏ zài nĭ xīn què bù jiŭ jū]
'我在你心却不久居' means 'I am in your heart but do not reside for long.' This implies that despite a place temporarily being found in someone’s mind, there’s uncertainty about future staying power. Such expression usually conveys feelings related to fleeting moments of intimacy followed by separation, expressing a transient nature between two hearts that connect before parting.
