This is kpop and every group is a threat to other group, There is no reason for fans to act all sugary with other fandoms
Idols might act friendly with each other but deep down they know they're a threat to their own popularity, they harbour ill feelings but try to hide for that perfect image
Don't tell me nayeon is not jealous of Jennie or NCT with BTS
there's is no reason for fans to butter up other fandoms just tear them down and make your favs feel special
