原谅我久溺深海只爱他
[yuán liàng wŏ jiŭ nì shēn hăi zhĭ ài tā]
'Forgive Me for Loving Only Him While Being Deeply Submerged.' In this expression, 'the deep sea' symbolizes a state of emotional entrapment. Despite the difficulties and perhaps isolation of these emotions, their feelings for this person remain unwavering and unrequited.
