这颗心只为你而跳动这颗心只为你而停止
[zhè kē xīn zhĭ wéi nĭ ér tiào dòng zhè kē xīn zhĭ wéi nĭ ér tíng zhĭ]
This Heart Beats Only for You, And Stops Beating for You as Well. It signifies complete devotion, expressing love and affection exclusively for one person to the point that living itself depends on this beloved individual.
