分手那天你决绝离开
[fēn shŏu nèi tiān nĭ jué jué lí kāi]
'On the Day We Broke Up, You Left Decisively.' It describes the scene during a breakup. This could reflect memories where the other party left decisively at the moment of separation. There may be elements of shock or pain left with them by this resolute departure after what seemed like significant relational ties.
