我就那么一颗心
[wŏ jiù nèi me yī kē xīn]
In English, it translates as “I only have one heart”. This expresses sincerity and faithfulness in feelings. It can imply a longing or declaration: 'I only love you, I don't entertain thoughts about others'. Or more broadly, ‘my heart isn’t divided - all of me belongs wholly to one place or one idea’.
