心在咫尺路在天涯
[xīn zài zhĭ chĭ lù zài tiān yá]
This username expresses a sense of longing where one feels close emotionally (心在咫尺 - the heart is near), but physically or realistically far away (路在天涯 - the road is at the end of the world), conveying that while two souls are connected by feelings, their paths are too different to be together.
