执念虐心
[zhí niàn nüè xīn]
Translating as 'Tortured Heart Due to Obsession,' '执念虐心' expresses the agony derived from intense obsession. '执念 (zhínìan)' indicates a stubborn fixation on a thought or emotion which cannot let go. This usually leads to suffering internally because desires are not met or realities disappoint expectations, especially related to unrequited feelings or lost dreams haunting repeatedly within the heart without rest.
