I still think that she'll never be able to shed her cute image completely.
She may look mature in terms of styling, makeup, clothings but once she starts talking, her natural aegyo ooshes out again. Haha,and when she laughs and talk, it's cute. For some reason, i always think that her voice is so sweet and cute especially when she talks japanese, she sound like some kind of anime character.
She's naturally cute and there's nothing wrong with that cause she's not acting it out.
I still love her cute image but i also love her mature image but for me, she's forever the cute maknae of kara.
