Jennie had one properly promoted single, but multiple songs. I don't think all the BTS members had a promoted single before resigning, but all the BP members did.
Multiple songs? I admit i don't know every single bp song but i only know solo. And i know that rose, lisa and jisoo got two solo songs. Obviously the members getting solos wasn't forbidden. But the number of songs is beyond embarrassing.
Bts didn't promote them because they weren't solos, they were solo songs on bts albums. Like rose's hard to love on the latest bp album. All the members should have gotten solos on bp albums.
Bts have promoted their official debuts that started last year
BP only has 30ish songs in total in seven years, i don't know why would i expect them getting proper EP's
Anyways, i hope the girls get good contacts from whoever they choose to sign
