Nah, I don't think they'll be friends.
At this point, the og FL just wants to take everything for herself and not care about anyone but herself.
She's a 4th generation chaebol who did what she wanted back in her world, so don't expect any chance for her to be good and befriend the MC. She basically tried to kill the MC in the first few chapters she was introduced so that tells you something.
Yeah, I think this is worth a read. The conflicts are generally light, the relationship between the female lead and the male lead is quite healthy—with no "misunderstanding" arcs—and a big plus is that you get to look forward to the original female lead’s malicious schemes, which ultimately just end up embarrassing her instead. Oh, and there’s also a plot twist toward the end. So give it a try

I always get my hopes up, and then they make the og FL a rival. Can we just have a smart woman who's world doesn't revolve around the MLs??? Or did "Beware of the Villainess" left the bar too high for my standards?
I might marinate this, bc I wanna skip the rivalry arc... I will keep my hopes up that they will at some point become friends...
