They perfectly understood how trend is working now and how everything go through Tik tok now
They are so active there compare to some groups and their tik tok are often just them having fun and doing trends compare to other groups where 95% of their tik tok is use to promote their songs and try to make their challenge go viral
They also gain a lot of fans these days very quickly because people enjoy how much they interact with their fans and not just big account
They literally interact with any account tagging at the point it even become a joke for them
Which is something that kpop groups doesn't really do the time to do outside of weverse or bubble
Their comment are also clever and "trendy" because they literally comment like any young person would do
And their answer doesn't seem as "control" than what other groups do it feels pretty raw in their interaction with fans
