I'm unsure how popular the show is but it seems her role in this kdrama isn't that big. So, that might be part of the reason why she's not seeing a significant boost. It does seem odd because actors on netflix usually see a significant boost in IG followers.
Happy to see Chaeryeong rising. Hopefully this leads to a solo this year.
I didn't even know it was out yet. I thought it was still "coming soon"
