I don't have a bias in NewJeans, but the answer for me is undoubtedly Hanni.
She manages to capture not only the hearts of the public more than any of the other members it seems, but also captures the essence of what it means to be an idol.
It is rare to have so much obvious star power as Hanni, while maintaining an image and persona that seems so relatable and approachable. It feels like she's one of us. She's chronically online, posts memes constantly, is a serial yapper and used to spend literal hours vibing with fans on Phoning.
She just seems to be everyone's favorite idol these days, and the fact a bill may be named after her in the future is only going to add to her legend.
For a foreign idol to be so popular in Korea is virtually unheard of, yet it was Hanni who had the stage of the year in 2024
Even a renown animation studio like Pixar is enamored with Hanni
She obviously has the skills, be it singing, dancing, songwriting, playing the guitar, but I think being the quintessential idol is a lot more about your ability to appeal to the public and attract lifelong fans than it is about being the most talented or skilled.
That's my pick. Hanni.
