吻过你的唇却不是你爱的人
[wĕn guò nĭ de chún què bù shì nĭ ài de rén]
A slightly melancholic phrase translating to 'kissed your lips but wasn't the one you loved.' The person uses this name to express their bittersweet sentiment: while they may have shared intimate moments with someone, they were not the beloved partner.
