在我心头开一枪死的是你
[zài wŏ xīn tóu kāi yī qiāng sĭ de shì nĭ]
Translated literally means ‘if you shoot through my heart, dead is you’. This carries heavy, complex meanings, potentially indicating that if they feel deeply hurt by somebody they will reciprocate; but also implies emotional vulnerability while hinting at retaliation.
