对你只是喜欢不是爱了
[duì nĭ zhĭ shì xĭ huān bù shì ài le]
In English, it means 'I just like you, not love.' By choosing this netname, the user wants to emphasize there's an obvious distinction between the emotions 'like' and 'love'. They also might be referring to some previous relationships, indicating they did care for someone but not deeply enough to be 'love'.
