我的心只为你跳无你无心
[wŏ de xīn zhĭ wéi nĭ tiào wú nĭ wú xīn]
My heart beats only for you. Without you I have lost my will to love anyone else anymore. A deeply romantic expression suggesting devotion to just one person exclusively beyond all measure - highlighting how much this specific love means more than everything else in their world.
