暧昧很近相爱很远
[ài mèi hĕn jìn xiāng ài hĕn yuăn]
This phrase conveys the subtle difference between affection without commitment (ambiguity) and being in love. It expresses that while someone may be flirtatious or friendly, these acts do not guarantee or lead to genuine romantic relationships, which could be near in physical action but remain distant emotionally.
