他未爱我入骨我却爱他如命
[tā wèi ài wŏ rù gú wŏ què ài tā rú mìng]
The literal translation would be 'He did not love me to the bone, but I loved him as life itself.' This username represents unrequited or asymmetric love. The phrase 'bone-deep love' symbolizes ultimate affection, so this expresses someone feeling their intense love was unmatched.
