一颗心只给一个人一份情只爱一个人
[yī kē xīn zhĭ jĭ yī gè rén yī fèn qíng zhĭ ài yī gè rén]
Translated as 'One heart for only one person; one affection for loving only one person,' this expresses fidelity, commitment and monogamous romantic love. It portrays the concept of being loyal and in love with just one partner exclusively.
