I define it girl as being popular with korean public (outside kpop fandom) and have real life impact like CFs & TV appearances, not just word of mouth.
Based on my observation I noticed that there are 2 type of it girl in Korea:
1. Mainstay (Yoona, IU, Suzy, Jennie)
2. Temporary (Seolhyun, Hani, Hyeri, Irene, Hwasa)
What did you think that make them received different attention?
Who is the current idol that have a chance or in the way to become the next it girl?
