Haeil reminds me toward Yoo Jung from Cheese in the Trap. Hopefully he's better than him. Btw, my bet is Minjae not a red flag, but lots of beige one.
I don't understand why her friend is still working, and other colleagues still fine with her. Very bad attitude and too childish. Other than that, I really need to know how she can convince the male friend to like her before as he seems to love her since beginning?
