未恨你负义只怨我痴心
[wèi hèn nĭ fù yì zhĭ yuàn wŏ chī xīn]
The phrase 'Wei Hen Ni Fu Yi Zhi Yuan Wo Chixin' roughly translates to 'Not resent you for unfaithfulness; merely lament my own infatuated love.' Here it expresses a heart-wrenching sense that while the other's betrayal isn't fully resented, frustration stems from recognizing and mourning one’s unwavering love leading to heartache.
