日出迟暮只守昕一人
[rì chū chí mù zhĭ shŏu xīn yī rén]
Meaning 'From sunrise till dusk I only cherish Xin alone', it romantically suggests eternal and exclusive affection or loyalty to one single person, regardless of time's passage. Here, 'Xin' may represent a special individual's name, or even dawn (昕 often associated with sunrise) signifying unwavering commitment through day and night.
