有一种爱叫看着你幸福
[yŏu yī zhŏng ài jiào kàn zhe nĭ xìng fú]
Translating into 'A type of love is letting you find happiness', this implies the noble feeling of loving someone so much so that their happiness even if not beside you brings comfort and satisfaction. A form of self-sacrifice in hope for the beloved's well-being.
