我爱哭却从不敢掉眼泪
[wŏ ài kū què cóng bù găn diào yăn lèi]
Means 'I Love Crying But Dare Not Shed Tears', which is quite paradoxical and expresses deep sorrow held back. This suggests the person has much pain but fears showing this through tears; hence there's also a feeling of being repressed in his heart that he wants others to notice but is too shy to express freely.
