来不及疼爱的爱人祝你幸福
[lái bù jí téng ài de ài rén zhù nĭ xìng fú]
Wishing happiness to someone whom one could not spend enough time loving. It conveys a regretful but hopeful sentiment towards a former beloved. It's about blessing someone after acknowledging that one might have failed to cherish that person adequately.
