They should celebrate ? For which reason exactly ?
Are we talking about the same BEP who after stopping to work with Twice and Apink announce that they'll continue to work with other gg in the future too
But they decided that now they'll keep their best music for StayC to help them rise to the status of top GG
I don't think it need to be celebrate when you see a producer do this kind of statement working with your favs
Yes they've limited number of artists working with them you can even say now ITZY jumps into APinks place because they've made a comeback and worked with different producers.
Also have you thought that maybe ITZY wanted to work with well known and popular Korean composers/producers?
Ah and one more thing, not just BEP, but all composers/producers of Cake are STAYC's / HighUp Team
