My bet is black hair likes MC so he asked Hyuna to seduce MC's crush so he can't have a chance with her
I said this because in some of the chapters 4, Hyuna said she was keeping a act or like she needed to play along. So I thought that her act until now was fake and was something black hair asked her to do. But I think this was due to poor translation.
I'm sorry if my explanation is a little confusing.
