爱人不是最好的朋友朋友再好也不能牵手
[ài rén bù shì zuì hăo de péng yŏu péng yŏu zài hăo yĕ bù néng qiān shŏu]
The username implies that although lovers can be very good friends, even if friends are as dear as lovers, they cannot have the same physical intimacy. It reflects the complexity and boundary of different relationships.
