我已深深囚入她心我已深深溺入他海
[wŏ yĭ shēn shēn qiú rù tā xīn wŏ yĭ shēn shēn nì rù tā hăi]
'Deeply imprisoned in her heart, deeply drowned in his sea' metaphorically describes being completely immersed or entrapped in someone else's emotions or love. It conveys intense feelings of love and dependency, with a touch of vulnerability.
