One of the things was, that I saw way more JPop-artists following KPop-idols than I expected, especially from the people you expect it the least. Sometimes its even people you may expect that they follow certain artist maybe but than see someone else and you be like "oooh oh ok" lol
Another thing I noticed is how many KPop and JPop idols follow accounts like Miley Cyrus, Billie Eilish or Justin Bieber o.o wow thats almost every 2nd account I looked at so far
I also noticed some people have more follow on Instagram than their groups get views on Youtube. I saw some JPop-idol with 200K follower and the most viewed song his group has is 30K on Youtube 
I also noticed the people who are on Twitter too are more odd on Instagram with who they follow than what they follow on Twitter
