What Does “CASE 143” Mean?

CASE 143 uses a numeric police code as metaphor, framing falling in love as an irresistible crime scene that the speaker cannot escape. The number 143 (I Love You in numeric shorthand) is embedded in the title as both a hidden message and a structural pun. The song blends romantic euphoria with Stray Kids' signature intensity, treating love as a force that overwhelms all rational resistance.
