Blacpink's success is an anomaly tbh. They go against kpop norms, barely releasing content/music in comparison to other kpop groups. Yet, the are the most popular girl group by far!
The thing is, I doubt this success could be replicated. BP's situation is unique, and Blinks are an unusually dedicated and resistant fanbase.
Even a top gg like aespa, suffered a bit after a longer hiatus.
Most Groups don't gain fans and hype during hiatus, but Blackpink does!
