On hyulari's ig story she was poking fun at joan with sunny. They were at a marble tabletop and sunny was saying joan's name and hyulari tagged her. When other beauty influencers low key make jabs at you also.
She sounds exactly like Jenn Im with the way she speaks and her facial mannerisms as she expresses. Joan doesn't have one creative bone in her body. Everything she does/buys/says is a direct copy of someone else whether it be a kpop idol or Jenn.
