不酷只有你很酷只聊你
[bù kù zhĭ yŏu nĭ hĕn kù zhĭ liáo nĭ]
The literal translation is: 'only you are cool, only talk to you'. It shows the specialness of one person in the eyes of the internet user, conveying a deep admiration or love toward a particular individual, indicating an intention of communicating only with them, which can be considered exclusive.
