i think the yaoi was mistagged, its been removed.
regarding the kpop thing in japan though, its not strange enough to be considered a plot hole. there are lots of japanese kpop idols (for ex: twice, izone, nct,..) the kpop agencies constantly hold international auditions for idol groups, and with japan being one of the major countries they promote in, japanese idols are sought out. even in produce101 japan, there were lots of japanese trainees who trained in korea.
There are so many holes I see in the plot already, but maybe we have to wait it out?
Like someone in a previous comment mentions how they are in Japan yet are talking about K-Pop which is in Korea? And Another commenter said that it has a yaoi tag, which is super weird because it looks like it is yuri??? Σ(  ̄□ ̄||)
Like if anyone has seen more chapters of this, can you explain what is going on? Because this is getting really confusing....
