念与北诗度她余生允他一世心若移动
[niàn yŭ bĕi shī dù tā yú shēng yŭn tā yī shì xīn ruò yí dòng]
'Think of Her and Spend the Rest of Her Life With Him, Promising Her a Lifetime Devotion That Is As Steady As Ever.' It portrays deep love and commitment where one person agrees to stay by the other's side forever unchanging in their devotion despite any challenges encountered along the way.
