我是爱神不会爱
[wŏ shì ài shén bù huì ài]
The user may be calling themselves 'Cupid but unable to love'. There's often an ironic twist with it because, despite representing 'the god of love', they're claiming they do not know how to love. This could be a self-deprecating way of saying that even though one has the potential or ability to give love, there are still difficulties in actually experiencing or expressing this emotion.
