kill this love definitely. i think rose should get the most for vocal parts or jennie should get the most for rap parts so ktl seems the fairest. and jisoo isn't just getting nothing but a good amount + she's paralleling rose so it shows she's a lead vocal.
playing with fire is probably the worst bc jennie gets to sing and personally i think jisoo should be treated like the lead vocal and jennie and lisa should both be sub vocals and main rappers.
