放不下的是你忘不掉的是你
[fàng bù xià de shì nĭ wàng bù diào de shì nĭ]
"Can't Let Go of You, Can't Forget You" - It reflects the strong emotional attachment and deep longing in one's heart that can be too overwhelming to let it dissipate. This person might find himself/herself always missing someone all the time.
