朝心开枪
[cháo xīn kāi qiāng]
This can be interpreted as 'Fire a Shot at the Heart'. In Western pop culture, there is a metaphorical saying: 'Shooting (into) one’s heart', typically describing falling in love deeply. But here, given the more aggressive term used - 'fire a shot' - it implies being wounded emotionally, probably referring to intense heartbreak or betrayal from an intimate relationship.
